Oldham was a chemist and DHARMA Initiative member who performed interrogations.[1]

On the Island


Oldham prepares to interrogate Sayid.

Horace Goodspeed brought Sayid to Oldham's tent outside the Barracks in order to determine Sayid's true identity. Oldham gave an unidentified drug to Sayid, which would apparently act as a truth serum of some sort. When Sayid started babbling about being from the future, Oldham concluded that he had dosed Sayid too heavily and did not believe Sayid's story. Oldham would appear to be the only DHARMA member who lived outside of the central Barracks complex. Sawyer described him as a "psychopath." Oldham appeared to enjoy music.

It seems highly likely that Oldham's job was to extract information from Hostiles captured by the DHARMA Initiative in their ongoing conflict. ("He's Our You")

He was probably killed along with other members of the DHARMA Initiative in the Purge, possibly defected to The Others prior to The Purge, or he may have left the island by some other means.
