Donald C. Sedlack, a retired stockbroker who participated in church mission work, died Thursday of autoimmune disease at the University of Maryland St. Joseph Medical Center. He was 81.

The son of Charles Sedlack, a Western Electric Corp. health benefits director, and Eleanor Sedlack, a secretary, Donald Charles Sedlack was born in Baltimore and raised in Stoneleigh.


As a teenager, he played catcher for Stoneleigh in the American Legion baseball league.

He threw out Southern High School star Al Kaline at second base the night before Mr. Kaline joined the Detroit Tigers in 1953.

"He reveled in telling that story through the years," said his wife of 60 years, the former Evelyn Sims, who met her future husband when both were students at Towson High School

Mr. Sedlack was a 1953 graduate of Towson, where he was an outstanding athlete and played varsity baseball, basketball and soccer. He was also elected prom king and senior class president.

He earned a bachelor's degree in 1957 in economics from Duke University, where he played varsity soccer and made first-team All Southern Conference, and was president of Phi Kappa Psi.

After marrying in 1957, he and his wife moved to Akron, Ohio, where he took a position in the marketing department of Standard Oil of Ohio. They later moved to Cleveland.

In 1968, Mr. Sedlack joined Eastman, Dillon, Union Securities & Co. at its office in the old Mathieson Building at Light and Baltimore streets.

Mr. Sedlack spent more than four decades at the Baltimore office of Blyth, Eastman Dillon & Co., which became Paine Webber and was later acquired by UBS AG.

After living in Glen Arm and Monkton, he and his wife, a former Baltimore County librarian, moved in 2001 to Easton.

"He had the opportunity of going to other firms through the years, but he felt a loyalty to the company and his clients," his wife said. "He was going to retire after we moved to Easton, but one morning he was dressed in a suit and said he had to finish up some things at the office. That took another eight years."

In Easton, Mr. Sedlack joined Christ Episcopal Church and did mission work in Mississippi after Hurricane Katrina as well as in Belize and Kenya.

His wife was a founder of the Talbot Interfaith Shelter, and he served on its finance committee. He was also a member of the boards of John S. Connor Inc. shipping company and the Talbot County Historical Society.

For more than 40 years, he enjoyed vacationing and fishing at Bethany Beach, Del., and played tennis and skied until he was well into his 70s. He was a world traveler and had traveled to more than 40 countries with his wife.

He was also an avid Orioles and Ravens fan.


In 2016, he and his wife moved to the Mercy Ridge retirement community in Timonium.

Mr. Sedlack was an active member of Timonium United Methodist Chruch, 2300 Pot Spring Road, Timonium, where a funeral service will be held at 10:30 a.m. Wednesday.

In addition to his wife, he is survived by two sons, Mark James Sedlack of Mays Chapel and Stuart Donald Sedlack of Woodbine; and five grandchildren.
