Resonantly-voiced English-born thespian John Patrick Horgan was best known for his affinity with the works of Arthur Conan Doyle, or, more specifically, Sherlock Holmes. He played the great detective several times on stage, notably in 1975 and 1990, as well as providing the character's voice on two audio recordings for the blind. Horgan was of Irish ancestry, the son of doctors. Rather than follow in his parents' footsteps, he dropped out of medical school and took up acting. He began working in television in 1954, his first recurring role being a romantic figure in The Gentle Falcon (1954), a BBC series based on a historical novel by Hilda Lewis. In 1964, Horgan married the American actress Irish McCalla. For a while, the couple lived in an apartment in Greenwich Village, Manhattan. By 1966, they had separated and Horgan spent most of his time on the West Coast cutting his teeth on prime time TV shows like Pistols 'n' Petticoats (1966), Görevimiz tehlike (1966), The High Chaparral (1967), Green Acres (1965), Uzay Yolu (1966) and Tatlı cadı (1964) (as an amorous English castle ghost). He also had a prolific run as Dr. John Morrison in NBC's daytime soap The Doctors (1963). For the big screen, Horgan narrated Woody Allen's mockumentary Zelig (1983). His final screen role was as a guest in Allen's Akrebin Laneti (2001).
