Tycho Brahe
Tycho Brahe was a Danish astronomer of the 16th century. The Tycho Project was named after him. (PROSE: The Last Sontaran) According to the Seventh Doctor, Brahe possessed a "scientific genius". (PROSE: Fable Fusion)
When Brahe was fourteen he witnessed a solar eclipse in Denmark. The fact that the eclipse was predicted inspired him to become an astronomer. (COMIC: Herald of Madness) He studied at Charles University in Prague. (PROSE: The Long Step Backward)
Tycho Brahe lost his nose in a duel with his cousin, caused by a disagreement over an equation that got "a little heated". The nose was replaced by a facsimile.
By 1601, Brahe became the court astronomer to Emperor Rudolf II. He took Johannes Kepler as a student and considered himself to be the world's greatest astronomer. While en route to the Gathering at Castle Houska, he and Kepler met the Thirteenth Doctor, Graham O'Brien, Ryan Sinclair and Yasmin Khan in Kokorin Forest in Central Bohemia.

After Brahe's death, his body was buried in a cemetery in Prague. In the 24th century, his body was unearthed by the Third Doctor and Sergeant Kandula during the search for the Tipping Device. The Doctor said he was "an old friend". (PROSE: Midnight in the Café of the Black Madonna)
