[1] Dyson played a number of roles in theatre, television and films (including in telemovies) but is best remembered as a versatile character actress in TV serials who became a familiar face to British viewers in a career spanning almost 50 years from 1949 until her death.

[4][1] Her most significant roles in this period included seven appearances in the series The Vise (first broadcast in the U.S. between October 1954 and December 1955, but not shown on TV in the UK until 1957-59) and a BBC adaptation of The Secret Garden in 1960.

She was written as a calm-natured, placid character who frequently had to act as mediator between her hot-headed husband and son Ken, whose upwardly-mobile aspirations were seen by Frank as a rejection of his family background.

Coronation Street was produced in Manchester by Granada TV while Dyson's home and family were now in London, and she did not feel able to commit to ongoing lengthy absences, so when her contract came up for renewal she declined to sign.

[10] Her only other long-running TV role came as the long-suffering wife of Arthur Lowe's character in the sitcom Potter between 1979 and 1983, but she continued to make cameo appearances in many top-rated shows such as Me and My Girl, London's Burning, Bergerac, Prime Suspect and Casualty until shortly before her death.

The service was officiated by Canon Bill Hall, Senior Chaplain of the Actors' Church Union, and attended by many friends, including William G. Stewart, with a reading from Judge.
