Adrienne Kramer

Brigadier-General Adrienne Kramer was the leader of the United States division of UNIT in the 1990s and 2000s. She was a friend of the Eighth Doctor and Alistair Gordon Lethbridge-Stewart.

History
She met the Doctor in his seventh incarnation in an adventure involving saving Washington, D.C. from disappearing up a time rift.

In 1997, Kramer worked with the Eighth Doctor, Sam Jones, and Carolyn McConnell to eradicate a horde of vampires living in San Francisco. (PROSE: Vampire Science)

In 2002, the Eighth Doctor phoned Kramer asking for help in dealing with the problem San Francisco was having with its ley lines. Kramer didn't think that UNIT would be able to help the Doctor and told him that he would have to fix the issue himself. (PROSE: Unnatural History)
