Born May 2, 1929, in Heidelberg Township, he was the son of the late Russell H. and Arlene M. B. (Semmel) Haas.

He married Delores J. (Reich) Haas in 1950 in Sacramento, Calif. while a sergeant in the U.S. Army.

They were married for 71 years.

He served during the Korean War, and then received high honors from the University of California, Berkeley graduating with a Master of Science degree in physics and a Doctorate in engineering science.

At Berkeley, he was inducted into the Phi Beta Kappa Honor Society for his high academic achievements.

He was proud to work at the former Bell Labs, Reading and Allentown, where he was part of different teams that developed the Picturephone®, various vacuum tubes, IMPATT diodes and much more.

He was a loving husband and father, a fun-loving grandfather and great-grandfather, and a witty and loyal brother and friend, who will be greatly missed.
