His most memorable role was as beloved TV dad Martin Lane on “The Patty Duke Show” (1963-66). The performance still resonates: TV Guide slotted him at No. 39 on its list of Greatest TV Dads of All Time in 2004.
Schallert would be familiar to many for his memorable appearance on the famous “The Trouble With Tribbles” episode of the original “Star Trek” series: He played Nilz Baris, the agriculture undersecretary who is outraged to discover that the furry, endlessly reproducing aliens have devoured all the grain.
Schallert served as SAG president from 1979-81 and oversaw a three-month strike in 1980 that centered around rates and residuals for pay TV, videocassettes and videodiscs and included a successful boycott of the year’s primetime Emmy Awards.
