Fitz Kreiner

Fitzgerald Michael Kreiner, or simply Fitz, is a fictional character in the Eighth Doctor Adventures novels based upon the British science fiction television series, Doctor Who. The Eighth Doctor first met him in the novel The Taint by Michael Collier — the character was co-created by Stephen Cole — and he went on to become one of his companions.

Character biography

Fitz was born in 1936 to Otto Kreiner and Muriel Tarr Kreiner at the Royal Free Hospital in Hampstead. His father died when Fitz was young, and his mother fell ill, forcing Fitz into foster care. During World War II, he was often subjected to beatings by other boys, due to his German heritage.

Fitz was 27 years old when he first met the Eighth Doctor and Sam Jones in 1963. He smoked, drank and liked to think of himself a ladies' man (which he is not). He often found himself out of his depth in futuristic and alien settings, but was always loyal to the Doctor and was the longest serving companion in the novels (55 novels to date).
