A most valuable player

Behind the plate

The film director’s origin story sounds like a Hollywood pitch on its own: An American baby is born in post-World War II Berlin to a Holocaust survivor and an American G.I. She grows up in thriving, mid-century Detroit, where she frequents Briggs Stadium and develops an unlikely obsession with baseball and little-known Jewish heroes. She earns a degree in psychology, completes a master’s in urban planning, and graduates law school – before drastically shifting course and becoming a documentary filmmaker.

The Spy Behind Home Plate hit theaters May 24.

“I don’t do well on multiple choice exams,” she says, alluding to the failed Washington, D.C., bar exam that inspired her to change careers.

Today, storyteller Aviva Kempner, BA ’69/MUP ’71, is an award-winning artist who has made a career out of celebrating obscure Jewish figures – including athletes, entertainers, and philanthropists. Her films include The Life and Times of Hank Greenberg (2000), about America’s first Jewish baseball star; Yoo Hoo, Mrs. Goldberg (2009) about media pioneer Gertrude Berg who created the first TV sitcom; The Partisan of Vilna (1986), about the Jewish resistance in World War II; and Rosenwald (2015), about the wealthy Sears philanthropist who built 5,000 schools for African-American children in the Jim Crow South

“So many American heroes never get the thanks they deserved during their lifetime,” Kempner says from her Washington, D.C.-based Ciesla Foundation. (Her home production office, in the basement of a traditional colonial, sits directly behind the one-time residence of former FBI director J. Edgar Hoover.)

Outside the limelight

In May, Kempner released her latest one-of-a-kind story, The Spy Behind Home Plate. The movie tells the true tale of catcher and American patriot Moe Berg, nicknamed “the brainiest guy in baseball.” The gloveman played for several teams between 1923-39, most notably the Brooklyn Dodgers and the Boston Red Sox. He also held a law degree, spoke multiple languages, and worked for a time on Wall Street between seasons.

But it’s his career after baseball that captivated Kempner. In 1943, Berg joined the U.S. government’s nascent wartime intelligence service, the Office of Secret Services (OSS). This was the predecessor of the Central Intelligence Agency. Before long, the polymath patriot, ballplayer, attorney, and linguist would prove to be an MVP of espionage, interviewing prominent Italian physicists who had inside knowledge of Hitler’s atom bomb program.

“The players loved Moe,” Kempner says. “The fans loved Moe. But it’s what he did out of the limelight that helped us defeat Hitler at a critical moment in history. That was his biggest hit: a grand slam for America.”

Home run

Kempner’s film about Berg showcases many of the hallmarks that characterize her well-researched documentaries: a self-effacing hero, quick-cut interviews that push the narrative pacing, and unique, archival footage.

In fact, Kempner was blessed to gain access to 18 unseen interviews stored in a Princeton University archive. The footage had long ago been recorded for an unproduced film on Berg. Kempner uses the clips to great effect and offers a fascinating look at this athlete who spoke several languages and wrote a classic Atlantic essay on the catcher/pitcher pas de deux.

Humor is central to much of the work coming from this writer/director/producer. In one sequence, Kempner reveals how Berg, as a catcher playing for Princeton in 1919 (no easy feat for a Jew), gave audible signals to his pitchers in Latin. When asked to describe his plan B, should the opposition decode his calls, the catcher answered, “We’ll switch to Sanskrit.”

The Spy Behind Home Plate also features home-movie footage shot by players on a 1934 All-Star exhibition tour to Japan. The traveling party included Babe Ruth (Berg was entranced by his niece), Lefty Gomez, and Lou Gehrig. Berg’s personal footage, shot secretly from the roof of a Tokyo hospital, may have proved valuable to the American Air Force when planning World War II bombing raids.


Berg's passport

Kempner’s interviews with contemporary figures focus closely on Berg’s post-MLB profile as an OSS spy. Convinced that physicist Werner Heisenberg was central to the German atomic bomb program, the OSS assigned Berg to attend one of his lectures in Zurich, armed with a gun to assassinate him on the spot. Wild Bill Donovan’s OSS also gave Berg a cyanide capsule to swallow if he was captured.

After speaking to the German scientist, the multilingual undercover agent was convinced Hitler was nowhere near building an atom bomb.

“Ironically, by forcing many prominent German Jewish scientists out of the country, the Nazis slowed down their attempt to build nuclear weapons,” Kempner says.

This vital intelligence was critical to America’s top-secret Manhattan Project that produced the nuclear weapons the U.S. used to attack Hiroshima and Nagasaki. (In a strange coincidence, Berg’s brother, Sam, was assigned by the Army to assess the impact of fallout from the Hiroshima bombing.)


Prodigious research informs Kempner’s films, which are released in theaters and on DVD, but are not streamed. Hours of fascinating extra material makes the DVDs ideal for classrooms with the support of funding from the Ford Foundation, the Foundation for Jewish Culture, personal donors, and more. All of Kempner’s films play at a wide array of alternate venues including churches, synagogues, community centers, and museums.

Kempner founded her production company, the Ciesla Foundation (a 501C-3 nonprofit), in 1979. Her films have received numerous awards, including top honors from the National Society of Film Critics, the New York Film Critics Circle, the Broadcast Film Critics Association and the CINE Golden Eagle Award. In addition, Kempner is a founder of Washington, D.C.’s Jewish Film Festival, and her home serves as a salon where she hosts author events, screenings, and fundraisers. It’s a tradition dating back to her Ann Arbor days in which her first attempt at philanthropy was a benefit for welfare mothers. Buddy Guy headlined that memorable event.

Chasing stories

Kempner, who earned some of her U-M tuition selling movie theater tickets, also spent her student years in the late ’60s as a reporter at the Michigan Daily. She points to that experience as ideal preparation for sourcing and tackling complex subjects — and breaking through the inevitable obstacles confronting independent filmmakers.

“Investigative reporting in Ann Arbor taught me how to create a story that uncovers the unknown, something I love to do,” Kempner says.

The Spy Behind Home Plate, inspired and financed by executive producer William Levine, opened in theaters nationwide in late May. For tour dates visit thespybehindhomeplate.org.


  1. Stanton Peele - Ph.D. Social psychology, 1971

    The NY Times reviewed the original book on Moe Berg, “The Catcher Was a Spy” (on which last year’s unsuccessful movie of that name was based. All that follows are the words of Times review of that book.

    While Berg had an unusual feel for languages as well as an encyclopedic knowledge of word origins, he not only couldn’t hit in any language (as some baseball wit once observed), he also didn’t speak any foreign tongue expertly, and certainly not Sanskrit. . . .

    But as Berg’s life wears on, he strikes the reader increasingly as a freeloader and a bore. As one uncharmed acquaintance said, “He regarded most people as living in a kind of vacuum until he enlightened them.” And as another added: “He was free form, and anything I can think of that he said was more or less designed to impress. I don’t think he was interested in most people except as they were interested in him.”

    More disturbingly, incidents crop up of what Mr. Dawidoff describes as Berg’s prurient interest in human crises and his attraction to women whose husbands were about to divorce them. There are stories of clumsy sexual passes, and an unsavory reference to excessive tickling of an 8-year-old girl. And toward the end of the biography the words psychotic and schizoid appear.

    In his final chapter, “The Secret Life of Moe Berg,” Mr. Dawidoff undertakes a psychobiography of his subject and plumbs what he has earlier hinted at. Berg was always blind to his real feelings, the author suggests, and nearly lost control of himself toward the end. What he could never resolve was his own love of baseball and his immigrant father’s stern disapproval of the game. Nor could he reconcile his father’s rejection of religion with society’s insistence on viewing Berg as a Jew. These confusions produced a sense of self-distrust. The way to avoid the pain of confrontation was to stay always on the run and let no one pin him down.

    Interesting dichotomy of bias.


  3. Paul Rubinfeld - MBA, 1966

    I missed Aviva Kempner’s first film, The Life and Times of Hank Greenberg, when it was shown at the San Francisco Jewish Film Festival. A few months later it was playing at a local theater. It was playing mid-week and I didn’t think I could fit attending the showing in my schedule. I called Ms. Kempner to ask her if there would be a DVD release. Her response was, “…go see the movie I need the money.” I obeyed and never regretted it. She told me one of her motivations for making the Greenberg movie was to counteract the Woody Allen, Jewish male nebish stereotype. I asked her if a film about the great Koufax was next. I recall that she said would like to a film about Sandy Koufax but he was far too protective of his privacy to subject himself to interviews. Her next film, Yoo Hoo, Mrs. Goldberg, provided me with insight into the prowess of Gertrude Berg, who created and starred in the radio and TV show. Prior to learning more about Ms. Berg, via Kempner’s film found the The Goldberg’s an embarrassing stereotype, essentially a Jewish-American Amos ‘n Andy.


  4. David G. Wise - UM Law 1967

    I would like to purchase the DVD and the book on Moe Berg. I belong to a history club that meets on the first Monday of every month at the Beirut restaurant in Toledo, and I would like to give a presentation on Moe Berg. I have previously spoken on Branch Rickey and Moses Fleetwood Walker who both had UM connections…..Dave Wise 900 Adams street Toledo, Ohio 43604 419-252-6228….Thank you….Dave Wise
