Richard Kiley

Actor (Gideon Seyetik) — Deep Space Nine

Distinguished American stage and screen actor (1922–1999), the original Don Quixote in Man of La Mancha, who played the flamboyant terraformer Gideon Seyetik in the Deep Space Nine episode Second Sight.

Richard Kiley was an American actor and singer who won Tony Awards for Redhead and for creating the lead in the musical Man of La Mancha. On screen he won Emmy Awards for The Thorn Birds, A Year in the Life and Picket Fences, and his voice is heard as the tour narrator in Jurassic Park.
His one Star Trek appearance was in the second-season Deep Space Nine episode Second Sight. Kiley plays Professor Gideon Seyetik, a celebrated and enormously self-satisfied terraformer who plans to reignite the dead star Epsilon 119.
When Sisko falls for Fenna, a projection created by Seyetik's unhappy wife Nidell, the professor frees her by piloting the shuttle into the star himself.
