In 1952, Jack Webb, actor-producer-director of Dragnet, needed a replacement for Barton Yarborough, who had played Detective Romero opposite Webb's Sgt. Friday.

A few actors filled in as Friday's partners until Alexander appeared in the newly created role of Officer Frank Smith, first in the radio series and then on television. The popular series ran until 1959. When Webb revived it in 1966, he wanted Alexander to rejoin him, but Alexander had just signed to star as Sgt. Dan Briggs on the weekly ABC series Felony Squad.
