Don Imus, Radio Host Who Pushed Boundaries, Dies at 79

Don Imus, who tested the limits of shock radio with his irreverent attacks on celebrities, politicians, racial and ethnic groups, women, gay people and practically anyone whose head stuck up out of the foxhole, died on Friday in College Station, Texas.

A publicist, Matthew Hiltzik, confirmed his death, at Baylor Scott and White Medical Center.

On his “Imus in the Morning” show on March 16, 2009, Mr. Imus disclosed that he had prostate cancer.

He was advised to have radiation treatments, but said he had chosen to treat the disease holistically.

Since 1999, many of these children had spent summers on his ranch near Ribera, N.M.
