George Gershwin by David Alfaro Siqueiros, 1936
Dear Friends of Diego,
 

MTT, Maestro Michael Tilson Thomas, a San Francisco musical legend, has passed away. I don’t know if he ever saw Pan American Unity. But he is part of the mural’s story.

In 2007 I came across an internet blurb that intrigued me. Composer George Gershwin had encountered Diego Rivera and Frida in Mexico in November 1935. Their connection was a complete surprise to me. The evidence was a postcard Gershwin had sent from Mexico City’s San Ángel Inn to a friend Mabel Schirmer in NYC. In the postcard George mentioned that Diego had shown him the newly finished Palacio Nacional murals. The postcard had gone from Mexico City to NYC and was then in Houston. The owner was not a fan of Diego Rivera because he’d had an encounter with Paulette Goddard, Charlie Chaplin’s wife. She couldn’t give me an image of the post card because she had gifted it. To MTT. The SF Symphony conductor was a devotee of George Gershwin. The postcard had traversed time (over 70 years) and space (over 5000 miles) and was now two miles away. MTT’s staff very graciously sent me this digital copy.

This postcard unlocked a new world. When I mentioned the postcard at a mural talk, Jean Strunsky confided that she had information to share and invited me to visit. She and her late husband Michael Strunsky ran the Ira and Leonore Gershwin Trust, a block away from SFMOMA. Michael Owen, a former City College library student, was their archivist. Their collection included more postcards, letters, and a Tehuana dress Gershwin had purchased with Frida’s help. George painted a portrait of his dear friend Emily Paley in the dress.

Later, prior to sending the collection to the Library of Congress, the Trust invited me over and privately shared with me copies of color pictures of the 1935 Mexico trip that George had taken. In return, I annotated the locations and people in the photos. Here is Frida modeling the dress in one of several pictures George took of her.

George Gershwin first met Diego in 1932 on a specially chartered car of a train going from NYC to Philly. The passengers, including composers Aaron Copland and Carlos Chavez, were headed to the premier of the Mexican composer’s symphonic ballet, H.P. (Horsepower) for which Rivera had designed the sets and costumes. According to Lucienne Bloch’s journal Frida was ill and couldn’t make the trip to Philadelphia, though photos seem to show her there. According to Lucienne, Diego, Frida, and George had sodas together in 1933 after a concert of her father’s, Ernest Bloch, music in NYC.

 

George Gershwin ultimately ran into Diego and Frida in Mexico. The October 1935 Broadway premiere of Porgy and Bess was poorly received by the music critics, the score was not operatic, the cast was Black. A dejected Gershwin escaped at the suggestion of his cousin artist Henry Botkin, who had taught George to paintGershwin serendipitously checked into the San Ángel Inn, across the street from Diego and Frida’s studios. They spent time together and gathered along with Isamu Noguchi, Miguel Covarrubias, David Alfaro Siqueiros, and others at a party for Gershwin hosted by socialite Estrella Elizaga. (Isamu had done a bronze bust of George Gershwin in 1929. In 1925 Miguel Covarrubias had done a Gershwin caricature for his book, The Prince of Wales and Other Americans.) In a 2018 phone interview from Wales, the late Cynthia Boissevain, Estrella’s daughter, told me that George played and sang Porgy and Bess for the guests. Though it was past her bedtime, the 11 year old Cynthia watched from the stairs. She directed me to their house on Paseo de la Reforma, where the party had taken place. (Photo of a grown-up Cynthia with Diego about 11 years later.)

 

In 1937 at a Beverly Hills party hosted by actor and avid art collector Edward G. Robinson to honor composer Igor Stravinsky, Gershwin met Paulette Goddard. He wrote to Emily Paley on March 16, 1937:

“Gladys [Robinson] sat me next to the most glamorous & enchanting girl in the west. Paulette Goddard. She is a really exciting creature. Gladys knows my taste better than I thought. The whole evening was grand, what with those pictures, Stravinsky, Miss P.G….”

Immediately smitten, they had a brief encounter. But four months later he was dead from an undiagnosed brain tumor. (Sadly, MTT died from brain cancer.) In 1937’s Shall We Dance movie; Gershwin’s long-time friend Fred Astaire sang “They Can’t Take That Away from Me” to Ginger RogersThe bittersweet song, written near the end of George’s life, reportedly refers to his feelings for Paulette. Gershwin had encouraged Paulette to go to Mexico to get her portrait painted by his friend Diego Rivera. She would not make it there until May 1940, but the visit irrevocably changed Diego’s life. (Below: That’s Nieves Orozco as the “attendant.” The other portrait is being painted by Irene Bohus. )

Divorced from Frida in late 1939, Diego was reportedly slated to marry artist Irene Bohus or his model Nieves Orozco (whom I interviewed). His infatuation upon meeting Paulette (he and Gershwin were not the first, nor the last) caused him to burn those two marital bridges. Paulette, however, was just passing through. So Diego remained single by default.

Frida was brutally interrogated by the police in the wake of Leon Trotsky’s assassination in August 1940. She was a “suspect” because Trotsky had lived in her Casa Azul and because she and her sister Cristina had unwittingly had the assassin Ramon Mercader over for lunch. The police probably didn’t know Frida and Trotsky had been an item. Alarmingly, the police accused, that since she was divorced from Diego and her father was German, that she wasn’t even a Mexican. Being a German national passing herself off as Jewish was not a good combination at the time. Diego feared for her safety in a country not unfriendly with the Nazis. On August 26, 1940 she was expeditiously naturalized a Mexican and applied for a visa. Her confidant Dr. Leo Eloesser had told her to come to him in San Francisco and a fragile Frida showed up in early September 1940.

Shortly after Frida arrived she was checked into St. Luke’s Hospital on Valencia. Diego orchestrated a liaison for her with Heinz Berggruen, his translator and chauffeur, to keep her engaged while he finished the Pan American Unity mural at the Treasure Island fair. It was still not half painted. On December 8, 1940, his 54th birthday, Diego re-married Frida in San Francisco’s City Hall. But their pre-nups stipulated that they would no longer be lovers. From papers Julia Bergman and I located in Canada, this stipulation was observed. There would be no infidelity because that was not part of the “deal.” (This was the last research trip Julia and I ever took. She passed away in 2017 after a 20 year friendship/partnership.)

Prior to this time Frida had only two solo shows. The first in late 1938 at the Julian Levy Gallery in NYC might have been influenced by Gershwin, who supported Levy’s film program. (Has anyone ever come across the colored drawing of Frida, which George said that he did?) The other show in early 1939 in Paris was supposed to have been managed by Andre Breton, but was botched and only salvaged by Marcel DuChamp and Mary Reynolds. Breton had met Frida when he came to visit Trotsky in Mexico and he wanted to foist her off as a Surrealist. She famously replied, “I don’t paint my dreams, I paint my own reality.” Frida’s only solo show in Mexico came shortly  before she died.

Frida’s early access to the limelight came mainly through Diego. Edward G. Robinson bought four of Frida’s works in 1938, but only under duress. Diego forced Robinson to buy them to acquire his own work as related to me by David and Karen Crommie, who interviewed Robinson as part of their first ever documentary on Frida. It was clear that Dolores Olmedo only bought Frida’s work under the same duress. The two women did not not like each other. (The Museo Dolores Olmedo has recently re-opened with its major Frida holdings.)

Earlier, Diego was “married” and had children with two other woman artists in Paris, Angelina Beloff and Marevna, who have been relegated to footnotes in his life story. Might the same fate have awaited Frida, if she and Diego hadn’t remarried?

On June 11, 1940 Frida had written Diego just after he arrived in San Francisco that she was being treated badly in Mexico because she wasn’t one of the upper tier of famous artists and above all because she was no longer his wife. (Escrituras, Raquel Tibol)

    ”…todas la demás gentes me tratan como su basuda desde que no tengo el honor de pertenecer a la élite de los artistas famosos y sobre todo que no soy tu mujer.”

If Porgy and Bess had instead enjoyed a better initial reception, history’s trajectory would have enscribed a different arc. Gershwin wouldn’t have gone to Mexico to run into Rivera and to later offer his suggestion to Goddard. In fact he would not have met Goddard if he had not exiled NYC for Hollywood. His brain tumor might have been diagnosed earlier. We would have had more of George’s music. Diego might have married Nieves. (Bohus had shown up in San Francisco pregnant by Diego, immediately disqualifying herself.) History’s outcomes balance on a knife-edge. Instead, we have Frida becoming a global phenomenon. Although he does not appear in the mural, George Gershwin’s pivotal role in our story is almost like a deus ex machina in a Greek play, an off stage agent driving the story.

Thank you for the gift of your Music and the postcard, MTT.

Abrazos,

Dear Friends of Diego,

One of Diego Rivera’s recurring themes in his U.S. murals is the reconciliation of Art and Science. He knew there was a synergy in their fusion. Our long-time partners, Cultural Heritage Imaging, have just published their 3D documentation of SFAI’s Diego Rivera mural, The Making of a Fresco Showing the Building of a City, 1931The mural is in pristine condition. Public access awaits the infrastructure improvements to re-open the old SFAI campus.

 
Like CHI’s previously published Diego Rivera’s San Francisco Masterpiece Virtual Preservation of “Pan American Unity”, these records, archived at Stanford, leave future generations analytical benchmarks for the physical state of these two San Francisco legacies, which can last centuries. Moreover, the mural was moved and data about the logistics is available. Atthowe, the art movers, recently published a synopsis of “moving the unmovable.” Here is a link to the UNAM’s team report about Wire Rope Isolators and Real-Time Vibration Monitoring. The mural has been blessed with high-end documentation by world-class entities.
 
Hopefully, we’ll get a chance in the future to generate a similar photogrammetric record for the City Club’s Allegory of California. Logistically, it is the hardest to record because of the physical constraints of a stairwell.
 
Antonio Sotomayor

A friend recently convened a group interested in local artist Antonio Sotomayor. The Bolivian-born artist had come to San Francisco in 1923 and had gotten a job as a dishwasher at the Palace Hotel. But he was soon “discovered” and became the hotel’s artist. The group included art historians from Grace Cathedral and Treasure Island, an art conservator, two scholars from the Bancroft Library, and owners of pieces by Sotomayor. My connection with Sotomayor dates back to December 2006 when Lynn Wagner, the daughter of Mona Hofmann, a Rivera assistant and friend of Sotomayor, gifted City College her mother’s remaining papers, which I picked up in Los Angeles. Lynn is the seven-year-old girl sitting and drawing in upper panel 4 of the Pan American Unity mural. She shared an anecdote that Diego would buy her “good” watercolors on the condition that she spent the money on things her mother wouldn’t approve of. Her mother didn’t approve of the pact, but she had a close relationship with Rivera. He wrote the “Queen of Sheba” near her mural image and gifted her a 1930 self-portrait lithograph, signed twice. This was the crown jewel of the treasures we received from the late, very generous Lynn.

 

Mona and her husband had commissioned a Richard Neutra Hillsborough house and had Sotomayor paint El Tigrero in the house. In 1934 Mona had assisted Rivera at Bellas Artes, when he recreated the destroyed Rockefeller mural; the original was smashed to pieces in the middle of the night on February 10, 1934. She was the first assistant to Rivera on Pan American Unity,  but had to leave for health reasons. She would be treated by Dr. Leo EloesserFrida’s doctor and confidant. In a marvelous coincidence, when I got home from the meeting I received a call from a local realtor, who had come across a Sotomayor painting in a Pacific Heights house she was selling. Several of us were able to see this piece.

 

Sotomayor painted murals at Grace Cathedral near the end of his life. His nearby house was at H3 LeRoy Place, which Grace and he occupied for 40 years.  In 2013 I was invited to tour the house, which was just as he left it. There was an autographed photo of Pierre Salinger, President Kennedy and LBJ’s press secretary. Pierre’s mother Jehanne (née Biétry) Salinger was a local art dealer, lecturer, and editor of Argus Art Magazine.  Also on display was a book dedicated to Dr. Leo Eloesser by Spanish Civil War medical comrades with an inscription ala “In solidarity we stood up to our elbows in blood…” San Francisco seemed like a smaller place then and the stories often overlapped.

 

Sotomayor was part of the Bay area artistic community drawn to Diego Rivera upon his arrival in 1930. The photo below is indicative of Diego Rivera’s influence.

 
 
Here is Rivera in 1940 with some members of The Family Club, a split off from the Bohemian Club. These are mainly artists Rivera met on his first 1930 visit. Left to Right, Standing Lucien Laubdt (Beach Chalet), Antonio Sotomayor (Grace Cathedral), José Moya del Pino (Coit Tower), Otis Oldfield (Coit Tower), William Gerstle (SFAI), artist Phil Little, architect Timothy Pflueger, seated are Diego Rivera and Charles Black (head of PG&E and Shirley Temple’s father-in-law).
 

Johnny Cumming

In a second coincidence, the memory of Johnny Cumming was invoked. In 2007 Marshall McLennan had contacted me to take exception with the attribution of the little boy in the lower center of the mural as Donald Cairns, Emmy Lou Packard’s son. Marshall insisted he was the figure and told me a story about Johnny Cumming. The artist was rooming at Marshall’s grandmother’s boarding house on Leavenworth and assisting Diego at the fair on Treasure Island. One day Johnny took Marshall to the fair. Rivera asked Marshall to model  as the figure of the boy in the drawing below. However, later when it was time to model for the portrait in the mural, it was Donald Cairns who got the gig. Rivera added the figure of architect Timothy Pflueger, where the surveying instrument is to the right of sculptor Dudley Carter. The red grid allowed the scale drawing to be enlarged to full size.

However, this wasn’t the only important information we found. We had a picture in which most of the figures were identified, except for one. The younger man in the center of the photo was still an unknown. On a hunch I sent the image to Marshall and he confirmed that it was Johnny Cumming, who he said had “flaming red hair.” This is where I went astray. In the roster of fair employees, there was a “J.E. Cumming.” I jumped on it and followed the trail, although it turned out it wasn’t our Johnny. Beware of imposters.
 

Recently, CCSF Librarian Lisa Velarde, was contacted by a relative of Johnny Cumming and in doing research in Julia Bergman’s Rivera Collection came across the real Johnny Cumming; John Noble Cumming. As Marshall had told me years ago, Johnny died in a B-29 crash late in WWII, not quite 24 years of age. In this picture, he was 20 years old. This picture has kept Johnny Cumming alive for me. It also turned out, amazingly, that Johnny had previously known Rivera in Mexico, when the Cumming family fled China in 1934. Johnny is reportedly a figure in Man, Controller of the Universe according to his family.

Dear Friends of Diego,

 

The long-awaited Diego Rivera Theatre will break ground on Thursday, January 22, 2026 from 2 to 3:30 pm. in STEAM 101 (the event has reached capacity). The 30-month construction project will finally give the Pan American Unity mural a fitting home. It will be on the western side of Frida Kahlo Way on the major east-west axis architect Timothy Pflueger inscribed through Science Hall. In 1940 Pflueger’s Science building housed the entire College academic and administrative functions.

It’s been a long haul for the mural, a product of the 1940 Golden Gate International Exposition’s Art in Action program on Treasure Island. It was originally intended to be placed in the reading room of a grand library that was to be Pflueger’s next major City College project. The 74-foot-long buon fresco mural, painted on wet plaster,  would form the center third of a larger mural, the rest of which would be painted in situ and not require steel-framed panels. Since that library project was still on the drawing boards, the question arose of where to store the mural panels. Both the DeYoung museum and the Palace of Fine Arts balked at the cost to move the heavy mural inside. Finally, in 1942 the 10 crated mural panels were stored at City College in a shed adjacent to the old men’s gym. The five upper 14’9″ square panels were the largest which could be shipped across the Bay Bridge in a vertical orientation, necessary due to the fragility of the fresco plaster. The five lower panels were half-height. Now the mural was tantalizingly close to its destination, but history always writes its own stories. When the US entered the war in late 1941, building materials were unavailable for non-essential construction. Soon after the war ended, Timothy Pflueger died on Post Street after a swim at the Olympic Club. It was not until 1961 that the mural was installed in the Little Theatre designed by Milton Pflueger, Timothy’s younger brother. At the fair the mural was displayed flat, elevated 14 feet. The accommodations to make the mural fit into the narrow theatre lobby were to curve the wall and have the mural panels form a stepped curve with the bottom edge elevated three feet off the ground.  Embedding the mural into the wall with steel rods functionally made the installation “permanent”. The concept of the mural’s longevity had not yet entered the design. In 1999 Francesca Piqué from the Getty Conservation Institute was invited to evaluate the mural. She had just done work at the Vatican and was impressed by the vibrancy of the colors and the quality of Rivera’s work.  She admonished me to think of taking care of the mural for the next 200 years. We cannot assign a value to the tremendous work done by SFMOMAAtthowe, Sheedy Crane, Nichols Concrete, and the multi-disciplinary team from Mexico City’s UNAM in safely extricating the fragile mural from its problematic anchorage. The collaboration embodied Rivera’s dream of Pan American Unity.  Now, provisions are designed to make the mural easier to install and to de-install in some distant future. This issue of long stewardship is currently being addressed in the care of Mexico City’s giant modernist mosaics, including Rivera’s.

Christopher Stork recently contacted me. He had acquired four 11″ x 14″ photographic glass plates, which were a full color separation of a mural image at Treasure Island. The photo was taken after Dudley Carter’s Goddess of the Forest, which had been in the way, was removed. The image was shot from across the room on the scaffolding for Herman Volz’s Organic and Inorganic Science mosaic, which now adorns the north portico of Pflueger’s Science Hall. Diego climbed Volz’s scaffolding daily to get an eye-level look at his own work in progress. Christopher’s question was whether these plates represented the images for the Life magazine, March 3, 1941 (page 52) pictorial. Another possibility was that they were for the poster that Timothy Pflueger wanted to print to raise funds for the expanded mural. Though we had a copy of a previous poster, it was a later version done most likely before the advent of the internet. Art Digest had also been interested in getting images. Above is a digital reproduction of the Black negative plate. (Christopher is interested in any insights from readers.)

Below is the almost finished Goddess at the GGIE Art in Action program. After the Fair, the Goddess was mounted in GG Park, where the lower 10 feet rotted due to an improper installation. The Goddess was acquired in 1986, truncated per Dudley’s specification, restored, and mounted in the lobby of the Diego Rivera Theatre, opposite the mural. When we tried to photograph the mural in 1999, it was again in the way. So, each combined upper and lower panels were shot individually and the film digitized. The five images were “stitched” together to depict the entire mural for use on the mural website and printed materials. The Goddess will find a new home near the mural, but not in front of it. Dudley Carter’s Mountain Ramcarved first and depicted in the mural, was recently installed in City College’s new Student Success Center.

Questions of how to display the mural came up as the new theater design evolved. To protect the mural it was suggested, that it be placed eight feet above the floor. Pflueger’s original design was to have the mural 14 feet off the ground over the library book stacks. But this idea had not been thought out and had it been built, I believe Pflueger and Rivera would have been disappointed. Neither ever saw the mural again.  Moreover, a reading room is quiet and not suited to student docents explaining the mural to visitors. Having seen many Rivera murals in Mexico, they often start at or very near the ground. Some said that the higher positioning was the artist’s intent. However, as Diego said about painting a mural: “You choose the wall, or take what is offered without a choice in the matter.” There was nothing in the figures that implied a preferred point of view. In fact, in letters to Rivera, Pflueger wrote that as you climbed some external adjacent stairs, you’d reach points where you got a good view at mural level. SFMOMA, which graciously supported my arguments, finally made the issue moot. They displayed the mural in the Roberts Family Gallery one foot off the ground. For 2-½ years 600,000 patrons were able to enjoy the mural up close and also from a distance. Many children and people in wheelchairs were able to have an intimate look at the lower panels, brush strokes and all. My favorite mural tour was for a legally blind woman.  She could get close enough to see blobs of color and we’d discuss what she was seeing.

Since this mural can last centuries, on our watch we will pass the masterpiece to the future in pristine condition. During the duration of the construction project, the two lead art conservators, Kiernan Graves and Anne Rosenthal, and their team, who have overseen the work on the mural up to now, will continue to monitor the work every 6 months, so there are no “surprises”, when it is time to install it.

 

This year MoMA’s Frida and Diego: The Last Dream will undertake a joint effort including the Met’s new production of El Último Sueño de Frida y Diego (May 14–June 5, 2026), composed by Gabriela Lena Frank with a libretto by Pulitzer prize winner Nilo Cruz. The opera which ran in San Francisco during the mural’s SFMOMA exhibition allowed visiting opera lovers from all over the world to see the mural. I gave a tour to the opera creators and was invited to see the opera three times. (Gabriela Lena Frank will debut a new Diego and Frida-based string quartet piece in February.)

Frida is as always in the news. In November her El Sueño (La Cama) set a record for a woman artist selling at $54.7M. Even a 2″ portrait was offered for sale at $15M by San Francisco’s Weinstein Gallery. The Frida Kahlo Foundation, based in New York, but involved with the new Museo Casa Kahlo, is proposing a new strategy of making digital twins of Frida’s paintings. This is a work around for the Mexican law which makes her works part of the national patrimony, which prohibits the works leaving Mexico, but also dissuades loans to Mexico of Frida’s works held outside the country.

Our mural can be investigated in extraordinary detail at Stanford hosts scientific images of Diego Rivera’s Pan American Unity MuralCultural Heritage Imaging will soon announce the Stanford website for the photogrammetry shoot of the SFAI Rivera mural. So far, logistical constraints have prevented a photogrammetric shoot of the Rivera mural at the City Club.


As the mural enters its next phase, we acknowledge some of those who helped steward the mural up to this point and have passed on. Well done, dear friends.
