Dr. William F. House, a medical researcher who braved skepticism to invent the cochlear implant, died on Dec. 7 at his home in Aurora, Oregon. He was 89.
The cause was metastatic melanoma, his daughter, Karen House, said.
Dr. House pushed against conventional thinking throughout his career. Over the objections of some, he introduced the surgical microscope to ear surgery. Tackling a form of vertigo that doctors had believed was psychosomatic, he developed a surgical procedure that enabled the first American in space to travel to the moon. Peering at the bones of the inner ear, he found enrapturing beauty.
