Chemical Heritage and Life Sciences foundations merging

Philadelphia's Chemical Heritage Foundation and the Life Sciences Foundation, of San Francisco, both founded by retired University of Pennsylvania professor Arnold Thackray, said they plan to merge next month.

The headquarters of the combined entity will be at the Chemical Heritage Foundation's museum and library on Chestnut Street in Old City, but the organization will retain offices on the West Coast.

The Chemical Heritage Foundation, founded in 1982, had $5.4 million in revenue in the year ended June 30, 2014. Its purpose has been to preserve and study the full history of chemical sciences.

The Life Sciences foundation was founded in 2010 and focuses on the history of biotechnology over the last 40 years. It had $1.9 million in revenue in the year ended June 30, 2014.
