He was also the corporation's co-founder. In the 1960s, Marcus was responsible for discovering the so-called Progenitor virus and decided to examine its potential as a biological weapon.

Lore & Background
In 1988, Marcus was assassinated on the orders of Umbrella's other co-founder, Oswell E. Spencer, who sought his research. After his corpse was dumped, the Queen Leech entered his body and reanimated it, gaining his memories and the ability to shapeshift. This entity believed itself to be the resurrected Marcus and orchestrated the T-virus outbreak in the facility and on the Ecliptic Express train as a means of revenge against Umbrella. The pair of Rebecca Chambers and Billy Coen eventually encountered this leech-controlling man, who was revealed to be Marcus' final experiment, the Queen Leech. After temporarily defeating it, they pursued it through the facility and ultimately killed it before the facility was destroyed by a self-destruct mechanism tripped by William Birkin.
