Donald J. Byers, 81, the former managing editor of the trade magazine of the Hotel Employees and Restaurant Employees Union (HERE), died May 2 at a medical facility in Eagan, Minn.

He had complications from a broken hip, said his son Duncan Byers.

Mr. Byers was managing editor of the Catering Industry Employer for 20 years before retiring in 1999. Before joining HERE, he was an information officer with the Federal Aviation Administration and worked at the Merkle Press and Kelly Press printing companies.

Donald Jason Byers was born in Washington. He graduated from Woodrow Wilson High School in 1950 and from Cornell University in Ithaca, N.Y., in 1954.

After college, he served in the Air Force for three years as an aircraft pilot and radar operations officer. He was then a civilian pilot and wrote articles for the flight-training magazine of the Aircraft Owners and Pilots Association.

Mr. Byers was a founder and director of the American Inventors Association and held four patents for innovations in aircraft technology, his son said.

He was a longtime Aldie resident before moving to Hampton, Va., in 1999 and then to Eagan seven years ago.

His wife, Julia Petzold Byers, whom he married in 1959, died in 2008.

Survivors include five children, Andrew Byers of Stephens City, Va., Jennifer Frederick of Seattle, Duncan Byers of Norfolk, Cameron Byers of Fallon, Nev., and Catherine Breet of Eagan; and 10 grandchildren.
