Dr. William Birkin was a virologist who worked for Umbrella Pharmaceuticals in the 1970s-1990s. One of the leading scientists behind the T-Virus and discoverer of the Golgotha Virus, he turned against the Umbrella Corporation after failing to achieve a promotion to its executive. The company's attempts to prevent an unauthorized deal with the US military served as a catalyst for the events of the Raccoon City Destruction Insident. - #ResidentEvil #William #Birkin
