Nadia Červenka

 was a Czech scientist.

In 1950, she befriended the Royal Air Force officer Squadron Leader Ian Gilmore while serving as a medic in Berlin. They shared several drinks as well as rations. Gilmore and his troops rendered assistance to the Berliners in rebuilding their city in the aftermath of the Second World War. Due to the increasingly contentious Cold War, his troops were eventually airlifted out of Germany with Červenka's assistance.

Červenka defected from the Soviet Union to the United Kingdom in 1958. She provided the Sen-Gen Facility with a neuro-chemical hallucinogen developed using a yellow fungus which was discovered in the crater created by the Tunguska Event on 30 June 1908. It was believed to be extraterrestial in origin.

By 1964, she was one of eighteen scientists working at the Sen-Gen Facility. Shortly before her death in that year, she was reunited with Gilmore, then a group captain, who was investigating the facility in his capacity as a member of the Intrusion Countermeasures Group.
