Kres Mersky as Ellen Shoenhammer in The Life and Times of A. Einstein.

E=MC2.

Can one famous formula-turned-phrase make a man? What does that recognizable formula say about the character of the person who created it?

The one-woman play The Life and Times of A. Einstein, coming to the Coachella Valley Repertory Theatre Friday through Sunday, July 21-23, explores these questions. Directed by Paul Gersen and starring playwright/actress Kres Mersky, the off-beat fictional comedy centers on Ellen Shoenhammer, the secretary to Prof. Einsteinโ€”although she is far more than just his secretary.

The character is loosely based on Einsteinโ€™s real secretary, Helen Dukas, whose duties included chauffeur, bodyguard and media liaison. She worked to keep his public image clear of scandal. She kept track of his dalliances and hid all of this damaging information protect his family. She was also the manager of all his business affairsโ€”not a small feat, especially when dealing with a busy โ€œgenius.โ€ After her death in the 1980s, much of her correspondence was uncoveredโ€”and thatโ€™s when so much was discovered about Einsteinโ€™s illicit affairs.

Mersky told me that The Life and Times of A. Einstein is a slice-of-life play, taking place on the great physicistโ€™s birthday. He is supposed to be holding a press conferenceโ€”but he is somehow unavoidably detained, so Ellen has to stand in for him.

โ€œEinstein was a celebrity then,โ€ Mersky said. โ€œPeople hid in the bushes to get photos of himโ€”like modern-day paparazzi.โ€

The play covers Ellenโ€™s long association with the Einstein family, including how she came to meet the great man. Most importantly, she talks about his extraordinary research that changed our perception of the universe. Ellen also perfected the art of answering and evading questionsโ€”often better than the talking heads on todayโ€™s TV news.

โ€œI always wanted to do a play about Einstein because of what he stood for,โ€ Mersky said. โ€œHe was a complicated, great man who whose ethos and belief in the imagination helped shape science.โ€

How did the play finally come about? โ€œItโ€™s actually a play I have been working on for 15 to 20 years. I loosely based Ellen on the real secretary,โ€ Mersky said.

I asked Mersky why Einstein remains such a popular figure today. โ€œHe is the worldโ€™s most famous refugee,โ€ she said. โ€œHe is also known for all his humanitarian work. In 1933, he helped create the International Rescue Committee that, even to this day, is active. He will always be relevant.โ€

Mersky said she enjoyed creating a character who is strong yet funny. That description could apply to Mersky as well; sheโ€™s a Los Angeles-based actress who has enjoyed visiting the valley over the years. Her acting credits include Revenge of the Nerds and the Charlieโ€™s Angels TV series. She even appeared on the legendary yet short-lived The Richard Pryor Show.
