The show had its premiere on ABC in 1960 and aired, moving to CBS, until 1972. But Mr. Considine pulled out in 1965; his character married his girlfriend, played by Meredith MacRae, and moved away. (To fill their shoes, more or less, the family adopted a neighborhood boy, Ernie, played by Barry Livingston, Stanley’s younger brother.)
Timothy Daniel Considine was born on December 31, 1940 in Los Angeles. His father, John W. Considine Jr., was a producer whose films included “Broadway Melody of 1936”, “Boys Town” (1938) and “Young Tom Edison” (1940). His mother, Carmen (Pantages) Considine, was the daughter of Alexandre Pantages, founder of the vaudeville and cinema chain.
His paternal grandfather, John Considine Sr., was Pantages’ biggest rival. His uncle was columnist and author Bob Considine.
As Timmie Considine, he made his film debut at age 12 in “The Clown” (1953), Red Skelton’s revisit of the sentimental 1930s drama “The Champ,” which starred Wallace Beery and Jackie Cooper, 9 years. The Times review called Timmie “correctly melancholic, earnest and manly” as the son of a run-down alcoholic comic.
He followed that with TV spots, from “The Ford Television Theater” to “Rin Tin Tin”, and four films. Then Disney came along and brought him a decade of success and popularity, including playing the nephew of a Revolutionary War hero in the series “The Swamp Fox” (1957-60), starring Leslie Nielsen and the Franklin D. Roosevelt’s teenage son in film. “Sunrise at Campobello” (1960), with Ralph Bellamy.
Leaving “My Three Sons,” Mr. Considine made six television appearances in five years and had a memorable scene—playing a character credited as Soldier Who Gets Slapped—with George C. Scott in the movie “Patton” ( 1970).
He acted even less over the next 50 years, appearing on screen once or twice a decade and playing his last role as a judge with a gray beard in the thriller “Ray of Sunshine” (2006).
