Jack Smith (31 May 1898, The Bronx, New York City – 13 May 1950, New York City) was known as "Whispering" Jack Smith and was a popular baritone singer in the 1920s and 1930s who made a brief come-back in the late 1940s. He was a popular radio and recording artist who occasionally appeared in films.

Beginning in 1925, Smith generated a steady stream of Victor and HMV recordings in the U.S. and in London, where he performed periodically in stage revues. When he wasn't accompanying himself at the piano, Smith relied upon someone else to tickle the keys or strum a guitar. His 1926 recording of "When the Red, Red Robin Comes Bob, Bob, Bobbin' Along" featured special guest whistler Carson Robison.
Smith also sang with various society dance orchestras. Smith's biggest hits were "Gimme a Little Kiss, Will Ya, Huh?" and "Me

Smith was back in England for the opening of Will-o'-the-Whispers at the Shaftesbury Theatre on April 4, 1928, and performed in front of enthusiastically receptive audiences in Berlin during August of that year.

Smith’s "disarmingly intimate, polite, and velvety smooth delivery … distinguished him from everyone else." One reviewer in
describing his "whispering" style said that "His art was the epitome of understatement." Another indicated, "With a pleasing stage presence, and a genial manner, Whispering Jack Smith establishes contact with his audience just as soon as he sits at his grand piano, and he wins more applause with every song."

In 1930 Smith went to Hollywood, where he appeared in one of the first talking motion pictures, Cheer Up and Smile, during which he sang "You May Not Like It -- But It's a Great Idea." Whispering Jack Smith continued to perform throughout the 1930s, although his popularity gradually waned as styles changed. He staged a modest comeback in 1940 and made a handful of sentimental recordings, but quickly lapsed back into a rather early retirement.
Out of place in an increasingly rude and clamorous world, he died of a heart attack at the age of 51 in New York, 13 May 1951. He is buried next to his mother Anna Schmidt at St. Raymond's Cemetery in the Bronx, New York City. His grave is unmarked. He was survived by his wife, Marie. (info edited from Wikipedia & AllMusic)
