Kinch and Baker in Hogan's Heroes. Fuji in McHale's Navy. Barney in Mission Impossible. Diahann Carroll as the lead in Julia. Gail FIsher as Peggy Maxwell in Mannix. Lloyd Haines and Denise Nicholas as the leads in Room 222 ( with several African-American supporting characters) Clarence Williams III as Linc in The Mod Squad. Rockne Tarrington as Rao and Manuel Padilla, Jr as Jai in Tarzan. Hari Rhodes as Mike in Daktari. Kam Fong and Zulu in Hawaii 5-0 Henry Darrow and Linda Cristal in the High Chaparral. Don Marshall as Dan in Land of the Giants. That's just off the top of my head for people of color on TV shows during TOS's run.
Mission Impossible had Cinnamon Carter (Barbara Bain). The Girl From UNCLE had April Dancer (Stephanie Powers). Get Smart had 99 (Barbara Feldon) Honey West in Honey West (Ann Francis) Though that was more of a PI show, but she had gadgets. Tiger (Arlene Martel) and Marya (Nina Talbot) were reoccurring characters on Hogan's Heroes. Both were Allied spys.
Thank you for reminding me about
Hogan's Heroes -- that's brand new this season, and I did notice.
Daktari is also '65, but sadly, it's one of the very few shows I wasn't able to get for my station.
Honey West is a toughie -- yes, it stars a woman, but it's got more sexism than
Burke's Law ever did. Good call on
Get Smart. 99 is, indeed, a woman, and she's got a Julie Newmar comedic energy about her. She also, however, immediately falls in love with Maxwell Smart...
Mission Impossible hasn't come out yet (I haven't gotten to '66!). Of course, it's filmed next door to
Trek at Desilu, so its progressive bonafides make sense. Greg Morris has appeared in some shows prior, too (
The Fugitive, frex).
Tarzan is '66, so I haven't seen it. Ditto
Girl from UNCLE; that's a good catch.
That's all the contemporary shows.
Mannix comes out in 1967 (also Desilu). Ditto
High Chapparal.
Julia comes out in 1968 (two seasons after
Trek). Ditto
Mod Squad,
Land of the Giants, and
Five Oh.
Room 222 comes out in 1969, after
Trek is over.
So, I think it's safe to say that
Trek is definitely a standout for '66, and certainly for featuring a Black woman as an officer on the bridge (even if her portrayal is not always ideal). Definitely Jane Foster level important. And remember that the Trek pilot was filmed in '64 and featured a woman as
First Officer! Had the show been picked up for '65, it would
really have stood out (would Nichelle Nichols have been signed? I don't know -- she was already in Roddenberry's orbit, viz.
The Lieutenant).
