Hyder Rollins Dies; Economist Murdered

Hyder E. Rollins, successor to George Lyman Kittredge as Gurney Professor of English Literature, died last Friday in Cambridge. He was 69 years old.

A teacher of many scholars and a leading authority on John Keats, Rollins completed his monumental edition of "The Letters of John Keats" just before his death. In addition to his work on the early Romantic poets, Rollins was also an authority on the ballads of the Elizabethan period.
