Art was sort of in my blind spot as I grew up, too---but looking back on it now, it's impressive---on the air in L.A. beginning in 1952, on KGFJ, KFWB (pre-Color Radio), KXLA (the predecessor to KRLA), KPOP (the predecessor to KGBS) and KDAY.
It was while at KPOP that Art hit on the idea of licensing oldies, putting them in a collection of albums and selling them. He founded Original Sound and ran it for years. The label even had one original hit---Sandy Nelson's "Teen Beat" in 1959.
Art focused on Original Sound exclusively from 1961 until 1970, when he went back on the air at KPPC, XEPRS (which had been XERB up until 1971) and KRTH.
It was Art, as General Manager of KRLA, that brought that station back to life and relevance after it had fired everyone save Johnny Hayes and gone automated. Art came aboard in 1975, hired Bill Pearl and Tom Greenleigh to program in 1976, and in the winter '76/'77 book, actually beat KHJ in the ratings.
He left KRLA when Greater Media bought it in '79, but came back as a jock in 1985 and had a 13-year run before KRLA changed format. At which point, he went across the street to KCMG (later KHHT) and did 17 years. And then did another two on KDAY.
Legendary, inspirational and totally his own thing---a uniquely L.A. radio story.
