Robert Vaughn (1932–2016)

From the New York Times obituary:

[N]o character he played was as popular as Napoleon Solo. From 1964 to 1968, in the thick of the Cold War, millions of Americas tuned in weekly to The Man From U.N.C.L.E. to watch Mr. Vaughn, as a superagent from the United Network Command for Law and Enforcement, battling T.H.R.U.S.H. (Technological Hierarchy for the Removal of Undesirables and the Subjugation of Humanity), a secret organization intent on achieving world domination through nefarious if far-fetched devices like mind-controlling gas.

Far-fetched? Napoleon Solo and fellow agent Illya Kuryakin (David McCallum) were major inspirations in my espionage-filled boyhood. This post has a couple of details.
