A memorial service for the late Thom Weyand will be held at 11 a.m. on Saturday, September 27, at the National AIDS Memorial Grove in San Francisco, according to the Bay Area Reporter. He was its longtime former executive director. He died Tuesday, August 12, from acute leukemia. He was 63.

The acute leukemia surfaced in 2013 as a secondary cancer 14 years after Weyand was diagnosed with non-Hodgkin’s lymphoma (NHL), an AIDS-defining cancer. He shared his battle as an HIV-positive man fighting NHL in the January 2001 issue of POZ. At the time, he had been pronounced cancer-free.

In 1997, Weyand became executive director of the grove. He went on disability in 2001 and served as a grove trustee since 2003. Prior to the grove, he was development director for the National AIDS Memorial Quilt. In 1996, he helped raise $10 million to bring it to Washington, DC, to display on the National Mall.

Born in Buffalo, New York, Weyand moved to San Francisco in 1976, working at the San Francisco Ballet. He settled in Maui for 13 years, working as executive director of the Maui Philharmonic Society. After meeting Terry Huwe, he moved back to San Francisco in 1990. Weyand and Huwe got married in 2013.
