"There were positives. Many of the deceased were enemies of HYDRA."
―Lingenfelter to Daniel Whitehall[src]

Doctor Lingenfelter is a scientist in the employ of HYDRA under Daniel Whitehall.


Daniel Whitehall, the leader of a HYDRA cell, charged Dr. Lingenfelter and her team of scientists to find a way to duplicate the powers of the Obelisk. Using supplied cell samples from a victim of the Obelisk, Lingenfelter and her team believed they found a way to do so.

Whitehall decided to test the method at the wedding of Pete and Mariah Leitner as many who attended were HYDRA’s enemies. However, the results were not to Whitehall's liking. Only a few of the wedding guests and United States Navy officers died.

Later, Whitehall gathered Lingenfelter and his top scientists to voice his displeasure at the failed demonstration. Jemma Simmons, who was undercover at the time for Director Phil Coulson, assured him that given more time to study it, the Obelisk could be used as a weapon of mass destruction.[1]
