Gerald Hurst, American chemist and academic (b. 1937)

Gerald "Jerry" Hurst (June 16, 1937 – March 11, 2015) was an American chemist and fire investigator. Before becoming noted for arson investigations, Hurst designed explosives for warfare, invented a binary explosive device known as Kinepak and developed an improved chemical compound to create Liquid Paper. He also devised an explosive called Astrolite as well as the Mylar balloon.

Hurst provided consultation or expert testimony in several high-profile arson cases, including that of executed Texas death row inmate Cameron Todd Willingham. His work also led to the parole of convicted arsonist Sonia Cacy and the release of Ernest Ray Willis, who had spent 17 years on death row in Texas.
