Year-ending memories include those of people who made marks in entertainment before passing. In 2011, they included a significant number of behind-the-scenes talents whose television efforts endure. Andy Rooney: It's a sad irony that the pundit's death came only a month after he signed off from his longtime post on CBS' "60 Minutes." Love him or not, he was a total original.
Peter Falk: The actor had plenty of work under his belt -- or his trenchcoat, as it were -- by the time he took on the character that would be his signature, folksy police detective Columbo.
James Arness: The makers of "Gunsmoke" wanted John Wayne, who recommended Arness to play Marshal Matt Dillon
thus giving television one of its greatest Western heroes.
Harry Morgan: One of television's most reliable supporting players, the veteran actor who was the fatherly Col. Sherman Potter of "MASH" also was the good-humored Officer Bill Gannon of the 1960s reboot of "Dragnet."
Jeff Conaway: Struggling actors everywhere got an image boost from this performer's "Taxi" work as cabbie Bobby.
Jackie Cooper: An actor since childhood ("The Champ"), "Hennesey" television star Cooper became one of the medium's most prolific directors.
Sherwood Schwartz: If not for this veteran producer, viewers might never have gotten to know "The Brady Bunch" nor the castaways of "Gilligan's Island."
Leonard Stern: Another producing titan, Stern was instrumental in getting "Get Smart'' on the air. He also mentored Rock Hudson's "McMillan and Wife."
Sol Saks: The man who created Elizabeth Montgomery's "Bewitched'' lived to be 100. Literally.
Bob Banner: "The Carol Burnett Show" and "Candid Camera" were among the numerous credits of this producer.
Jack LaLanne: One of television's first fitness gurus, LaLanne was still doing infomercials at the time of his passing.
David Nelson: Ricky's brother helped make his family's life the stuff of sitcoms in "The Adventures of Ozzie and Harriet."
