Mr. Cole said that Mr. Seibert was an "old-school coach."
"He was very stern with the players, and that was the era when you expected the kids to learn from the older kids," said Mr. Cole.
Frank E. Rhodes Sr. is a retired Atholton and Lake Wilde high school coach who coached the basketball and track and field teams. "We coached against each other, and he was a real competitor. After all, this was a guy who was a bomber pilot when he was 20 during the war," said Mr. Rhodes, who retired in 1985.
"Vernon was a throwback to the old days as a coach. He could scout out a high school team in two days and get them ready in a day, whereas it took the rest of us a whole week," he said with a laugh. "Vernon was a competitor from the word 'go.'"
He retired in 1986.
In addition to his work at Glenelg, Mr. Seibert founded the Howard County summer recreation program in 1965.
Mr. Seibert played softball and coached a team during the summer months. He was inducted in 1977 as the 39th member into the Maryland Fast Pitch Softball Hall of Fame.
He was an active member of the Ellicott City Post of the Veterans of Foreign Wars, where he played on its softball team, and the Old Timers Basketball Association. He was also a member of the First Lutheran Church of Ellicott City.
The longtime Columbia resident was married in 1950 to the former Barbara Mullins, who died in 2003.
Funeral services will be held at 11 a.m. Friday at the Harry H. Witzke Funeral Home, 4112 Old Columbia Pike, Ellicott City.
In addition to his daughter, Mr. Seibert is survived by two sons, Chris Seibert of Lake Wylie, S.C., and Kurt Seibert of Columbia, S.C.; two other daughters, Elise Devlin of Sadsburyville, Pa., and Jamie Hoffman of Onacock, Va.; companion Mary Johnson of Elkton; eight grandchildren; and a great-granddaughter.
