Born in Baltimore, he was the son of George A. Hardy, who founded the screening business, and homemaker Helen Fody Hardy. He was raised in Pikesville's Colonial Village and attended McDonogh School, where he played varsity baseball and football. As a guard in his junior year, he broke his left arm in two places; in the first game of the football season in his senior year, he broke the same arm. This time it took a metal plate to repair the damage. For the remainder of the fall, he played the saxophone in the school band and graduated in 1950, family members said.
He entered the University of Virginia. Family members said the night before a final exam in economics, Mr. Hardy sought guidance from a friend, a Zeta Psi fraternity brother and an economics major. After a brief synopsis and short outline of the course, Mr. Hardy, aided by his photographic memory, aced the exam. His friend, however, had to retake it to graduate two months later.
Mr. Hardy met his future wife, Helen Anne Welsh, on the beach at Ocean City during his college years.
After service in the Army Corps of Engineers in England and Wales, where he worked in air- base construction, he joined the family firm. In 1964, under his leadership, Accurate was transformed from a residential screen and storm window company into a firm that manufactures and installs commercial windows and storefronts. His son, G. Ridgely Hardy, is the third generation to head the company, family members said.
Mr. Hardy remained an advocate for McDonogh School and the Maryland Chapter of the University of Virginia. He occasionally hosted the Virginia Alumni Association's annual bull roast at his Long Green Valley farm.
Mr. Hardy and his wife were avid skiers and tennis players and traveled frequently to their vacation home in Ludlow, Vt. He was also a subscriber to the old Baltimore Opera Company and the Baltimore Symphony Orchestra. He was the 1969-1970 president of the Pikesville Rotary Club.
A memorial Mass will be offered at 10:30 a.m. Jan. 6 at the Carmelite Monastery, 1318 Dulaney Valley Road.
In addition to his wife of 57 years and son, he is survived by a daughter, Melinda H. Ryan of Lincoln University, Pa.; a sister, Nancy H. Davis of Baltimore; and eight grandchildren. Another daughter, Anne Talbot H. Brennan, a partner in the law firm of Whiteford, Taylor & Preston, died in 2009.
