Bonnie Franklin

Bonnie Franklin, who died March 1, 2013, is best known for her role as divorced mother Ann Romano on "One Day at a Time." Her daughters were played by Mackenzie Phillips and Valerie Bertinelli, with Pat Harrington as Schneider, the ever-present building superintendent.

Harrington provided much of "One Day at a Time's" comic relief. The sitcom ran from 1975 to 1984.

Franklin, Harrington, Phillips and Glenn Scarpelli, who played Franklin's boyfriend's son on "One Day at a Time," attend the TV Land Awards in New York in 2012.

Franklin's "One Day at a Time" character was one of the earliest divorcees on television.

Franklin, second from left, is seen with Richard Crenna, Jim Nabors, Linda Lavin, Bert Convy and Eve Arden in the miniseries "CBS: On the Air."

The "One Day at a Time" cast, including Franklin, Phillips, Bertinelli and Harrington, reunited on TODAY in 2008.
