William A. Ringler, English Scholar, Dies

William A. Ringler, a literary scholar whose 1962 study of “The Poems of Sir Philip Sidney� was acclaimed as among the most definitive works ever done on that 16th-Century Renaissance poet and courtier, has died. He was 74 and died Jan. 1 at his Pasadena home.

Ringler, a professor emeritus of English at the University of Chicago, most recently had been a senior research associate at the Huntington Library in San Marino. He also had taught at Washington University in St. Louis and at Princeton.
