Lincoln Case was a fictional character portrayed by actor Glenn Corbett on the 1960s American prime-time drama Route 66. Linc was one of three main regular characters on the program. His tenure began midway through the show's third season, when he was written in as a replacement for the departed Buz Murdock (played by George Maharis). Linc appeared in the final 32 of the program's 116 episodes as a sidekick to the character of Tod Stiles (played by Martin Milner).
The character has a certain historical significance. Linc was an Army [his Class A Uniform w/Class A 5th Special Forces Unit Patch and 1st Cavalry Division Combat Unit Patch on the right sleeve] (Linc may have a Ranger tab - unknown - but he is not wearing the Ranger Regimental Unit Patch) Ranger returning from service in the Vietnam War, which in the early 1960s was just beginning to become a major concern of ordinary Americans. His appearance made Route 66 the first dramatic television series to feature a recurring character who was directly involved in Vietnam. Many scripts and storylines of the show featured Linc trying to come to terms with his wartime experiences and adjust to civilian life. (Corbett, who played Linc, was a Navy veteran who had served in Korea.)
Linc's mother was portrayed by Linda Watkins in two episodes of the series. His father, Thomas, although an important character in Linc's tenure on the series, is never seen by the viewer and is only briefly heard as a voice over the telephone.
Author David Morrell is on record as being a huge fan of the Route 66 series and credits it for his inspiration to become a writer. [1]
Stirling Silliphant, the primary creator of the series and the writer of the episode in which Linc Case was introduced, later authored a series of novels featuring another Vietnam veteran character, adventurer John Locke.
