Lom was born Herbert Charles Angelo Kuchačevič ze Schluderpacheru in Prague to Karl Kuchačevič ze Schluderpacheru, and his spouse, the former Olga Gottlieb, who was Jewish.[4][5] Lom himself claimed that his family had been ennobled and the family title dated from 1601.[2]
His film debut was in the Czech film Žena pod křížem ("A Woman Under Cross", 1937) followed by the Boží mlýny ("Mills of God", 1938). His early film appearances were mainly supporting roles, with the occasional top billing. At this time he also changed his impractically long surname – to Lom ("breakage" or "a quarry" in Czech), because it was the shortest he found in a local telephone directory.[citation needed]

Lom starred as the King of Siam in the original London production of Rodgers and Hammerstein's musical, The King and I. Opening at the Drury Lane Theatre on 8 October 1953, it ran for 926 performances.[7] Lom can be heard on the cast recording.

During this period Lom starred in his only regular TV series, the British drama The Human Jungle (1963–64) as a Harley Street psychiatrist, over two seasons. Another low-budget horror film starring Lom was the witchhunting film Mark of the Devil (Hexen bis aufs Blut gequält, 1970), which depicted unusually graphic torture scenes. Cinemas reportedly handed out sick bags to patrons at screenings of the film.[8] He appeared in other horror films made in both the US and UK, including Asylum, And Now the Screaming Starts!, Murders in the Rue Morgue, and The Dead Zone.
Lom was perhaps best known for his portrayal of Chief Inspector Charles Dreyfus, Inspector Clouseau's long-suffering superior in several of Blake Edwards' Pink Panther films, beginning with the second movie in the series, A Shot in the Dark (1964). He also appeared in two different screen versions of the Agatha Christie novel And Then There Were None. In the 1975 version he played Dr. Armstrong, and later appeared in the 1989 version as General Romensky.
Lom wrote two historical novels, one on the playwright Christopher Marlowe (Enter a Spy: The Double Life of Christopher Marlowe, 1978) and another on the French Revolution (Dr Guillotine: The Eccentric Exploits of an Early Scientist, 1992). The film rights to the latter have been purchased, but to date no film has been produced.
Lom died in his sleep on 27 September 2012 at the age of 95.[
