Viral run-off left over from the Mansion IncidentВ was seeping into the city's water treatment plant, leading to a number of isolated infections occurring in the city. Unfortunately, Umbrella could not keep the truth from coming out indefinitely. Though Marcus was finally killed and the Umbrella Research Centre and Laboratory were destroyed by the S.T.A.R.S., Umbrella had to take steps to ensure that the public would never become aware of their illegal activities and went about blackmailing and bribing most of Raccoon's city officials in order to disgrace the S.T.A.R.S.

By 1978, the company's co-founder James Marcus had discovered the T-virusВ after introducing the Progenitor virus to leeches. This was all a cover, of course, and Umbrella's true work revolved around the research and development of biological weaponry. Over the years, Umbrella quickly expanded across the world, establishing itself as the world's leading pharmaceutical enterprise. Spencer, driven by his misanthropic worldview, became curious how the virus might be used to enhance the human race for the better and built up Umbrella as his means of exploring the possibility of remaking society in his image. During its early years, the company was almost solely dedicated to research on the Progenitor and its potential applications. Spencer and his associates James MarcusВ and Edward Ashford following their discovery of the Progenitor virusВ in Africa. Umbrella was founded in 1968 by Lord Oswell E.
