Cynthia Bolovan-Fritts, PhD

We lost a beloved member of Weinberger lab when Cynthia Bolovan-Fritts passed away in 2017.

Cynthia was the stalwart of the Weinberger lab for many years – in her 10 years here she was a mentor, scientist, friend and supporter both to our lab members, and to the wider scientific community.

Cynthia was born in Miami, received a PhD in Virology from the University of Cincinnati, and completed post-doctoral training with Ed Mocarski at Stanford.  She then came to the Weinberger lab where she spent the last 10 years.  Cynthia loved science and discovery above pretty much all else; she dedicated her career, and truly her life, to studying herpes viruses, and had an encyclopedic knowledge of these viruses.  She was exacting in her technique; to her the science and the lab were what really mattered.  She was an incredibly loyal and principled researcher – the glory didn’t concern at all, the work did.  Few people know that in 1994 during PhD, Cynthia cloned the first mutants of HSV-1 ICP34.5; these mutants went on to become the first approved oncolytic virus therapy, Amgen’s ‘oncovex’, now used to treat late stage Melanoma.  Cynthia never hyped this contribution, despite her claim to precedence. She was one of those unsung heroes.

Over her lifetime, Cynthia supported the preservation of nature and the environment, taking many trips to national parks across the United States with her husband Dan. When walking with Cynthia through San Francisco, one would often have to stop so that she could give money to the homeless.  She also loved music, taught herself to play the guitar, and attended over 50 Grateful Dead concerts. She was a true "dead head” - when Jerry Garcia passed away, Cynthia went to the Pacific Ocean with 5 dozen roses and threw the bouquet into the ocean as a tribute.

She is remembered as a wonderful colleague and friend who was always willing to go the extra mile to help, regardless of the size of the problem. She was a welcoming, generous, dedicated and beloved mentor to young students of virology. Many of her trainees are now in top PhD and medical training programs around the country, including Harvard, Yale and Duke.

As well as the impact she has made to so many aspiring and successful scientists, Cynthia’s memory will live on with the awarding each year of the Cynthia Bolovan-Fritts Research Excellence Award at the Bay Area Virus Meeting. This award will help young researchers embark on careers in research by providing some recognition.
