What is Frasier Crane's middle name?

Frasier Crane's middle name is Winslow, making his full name Dr. Frasier Winslow Crane.

The character was introduced in Cheers as a sophisticated psychiatrist and Diane Chambers's romantic interest before becoming the central figure in the Frasier spin-off. Kelsey Grammer played Frasier in Cheers, the original Frasier, and the later revival, so the middle name follows the character across the television universe.

Winslow is sometimes confused with the names of other characters or with invented alternatives that sound appropriate for Frasier's polished, old-fashioned personality. William, Winston, and Winthrop are plausible distractors, but they are not his canonical middle name. The name is also distinct from his brother Niles Crane and his son Frederick Crane.

Frasier's family history was expanded over time. His father is Martin Crane, his mother is Hester Crane, and his younger brother is Niles. Frasier later marries Lilith Sternin and has a son, Frederick. The character's full name is most useful when distinguishing him from his family members or from the many professional titles he holds, including psychiatrist, radio host, and television personality.
