Philip Rock, an Oak Park Democrat who led the Illinois Senate as its president during his 22 years in Springfield, died early Friday.
Rock, 78, first rose to the post of Illinois Senate president in 1979 and left the Senate in 1993.
His obituary describes him as "a Catholic, a Democrat and a Cubs fan ... but not necessarily in that order."
He is survived by his wife of 51 years, Sheila, as well as three daughters and a son.
State Sen. Don Harmon, an Oak Park Democrat, remembered Rock as a mentor.
