British actor (1928-2004)
Manfred Frederick Jaeger (29 May 1928 – 18 June 2004) was a German-born British film, television, theatre and radio character actor.
Biography
Jaeger was born in Berlin, Germany; his family moved to England following Adolf Hitler's rise to power. He was educated at Lord Weymouth's Grammar School, Warminster, and the Guildhall School of Music and Drama, from which he graduated in 1948, becoming a British subject two years later. He made his first theatre appearance in 1949, and his film debut, The Black Tent, in 1956. He went on to make further film, television and radio appearances until retiring in 1996. He died in June 2004 aged 76.
He is well remembered by fans of the science fiction series Doctor Who for his roles in three serials. He appeared as Jano in The Savages in 1966, and as Sorenson in Planet of Evil in 1975. In 1977's The Invisible Enemy, he appeared as Professor Marius, creator of the robot dog K-9; his performance was described by reviewer John Peel as "superb".

Why this record matters
The phrase “british actor (1928-2004)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The entry’s evidential value lies in the named roles, institutions and publications that can be tested against primary documentation. The source revision retrieved here is dated May 30, 2026. The linked authority identifier is Q5498128. VIAF identifies the subject as 12515993. The Library of Congress control number is no2012039110. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1928, 2004, 1948 and 1949.
A concise life account rarely captures disputed attribution, private networks or the changing language used to describe a career. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
