Walter E. Ershow, who flew 23 missions over enemy territory during World War II, died on Jan. 9 at the age of 89. The cause was heart failure, his family said. A part-time resident of East Hampton, he had been in declining health since October.
Born in Newark, N.J., on Sept. 14, 1923, to David J. Ershowsky and the former Minnie Reinfeld, he grew up in the Weequahic section of the city. He graduated from Weequahic High School and then attended Virginia Polytechnic Institute.
