Leslie Harold Collier (9 February 1921 – 14 March 2011) was a scientist responsible for developing a freeze-drying method to produce a more heat stable smallpox vaccine in the late 1940s. Collier added a key component, peptone, a soluble protein, to the process. This protected the virus, enabling the production of a heat-stable vaccine in powdered form. Previously, smallpox vaccines would become ineffective after 1–2 days at ambient temperature.
