Jenny Tomasin (22 March 1938[1][2] – 3 January 2012) was an English actress best known for her roles in Upstairs, Downstairs and Emmerdale.

[4] Her first major role came when she was discovered by Upstairs, Downstairs producer John Hawkesworth, who noticed Tomasin's photograph in a casting directory.

[3] Soon after, Tomasin joined the cast of Upstairs, Downstairs as Ruby Finch, the kitchen maid to the Bellamy family.

Although her career on Upstairs, Downstairs had made Tomasin a household name, she also felt that the role left her typecast.

[6][7] In 1985, Tomasin guest starred in the Doctor Who serial Revelation of the Daleks, the final story before the series went on an 18-month hiatus, as the character Tasambeker.
