George S. Irving, a Tony Award-winning actor who was in the original Broadway casts of “Oklahoma!” and “Gentlemen Prefer Blondes” and amused a wide audience pitching White Owl cigars on television, died on Monday in Manhattan. He was 94.

His daughter, Katherine Irving, said the cause was heart failure.

With his jutting jaw, wavy hair, commanding size and operatic baritone voice, Mr. Irving was a formidable stage presence.

“He didn’t need a microphone,” said James Morgan, the producing artistic director of the York Theater, an Off Broadway company where Mr. Irving reprised some of his roles in decades-old, short-lived Broadway musicals. “He had this incredibly resonant voice, and total precision of diction. You can hear him on recordings — his voice just pops out from everybody else.”

In one of those shows, “Enter Laughing,” in 2008, Mr. Irving revived the ridiculous, ribald number “The Butler’s Song” from “So Long, 174th Street,” as the musical was known when it closed after 16 performances in 1976. He showed anew the crispness of his enunciation — in this case stretched to farcical parody — and his talent for broad comedy.
