Todd Liddell Parchman, an investment banker who served on charitable boards, died of cancer May 9 at his Poplar Hill home. He was 70.

Born in Chicago, he was the son of Liddell Jackson Parchman Jr., a cattle buyer, and his wife, Marguerite Anderson. He attended Culver Military Academy and earned a degree at the University of North Carolina at Chapel Hill, where he was a Morehead Foundation scholar and played football. He received a master’s degree from the University of Chicago.

Mr. Parchman joined the First National Bank of Chicago and the Norwest Corp. in Minneapolis. While working in banking there, he met his future wife, Bryn Bjella Parchman.

He founded Signet Investment Banking Co. and moved to Baltimore in 1990 to join Ferris Baker Watts.

Mr. Parchman and a colleague, Lara Vaughan, established Parchman, Vaughan & Co. in 1996. He retired from his firm this year.

“My father was larger than life,” said his daughter, Kallan “Kallie” Elizabeth Parchman. “He wasn’t shy to make people laugh or have fun. His advice was to be aggressive and go for it.”

He and his family settled in Federal Hill on William Street and later relocated to Poplar Hill.

Mr. Parchman played golf at Baltimore Country Club and squash at the Maryland Club. He attended Ravens games. He developed an affection for lacrosse and often drove nine hours to watch his children compete in the sport.

He was an avid reader of history and biography. He read outdoors and smoked cigars with his dog at his side.

“My father was determined and driven,” said his son L.J. “Jack” Parchman III. “He was loyal to the people and institutions he loved and cared about. He was passionate about the power of education.”

His son Andrew Arley “Andy” Parchman said: “My father had a commanding personality — a life force — that his friends and family gravitated to. He was his own man, and had his opinions and views, and was not afraid to express them.”

He was an active Culver alumnus and a trustee of the Culver Educational Foundation, the University of Maryland, Baltimore Foundation and the Youth Outreach Foundation Inc.

He served on the boards of the Education Industry Association, the U.S. Lacrosse Foundation, the Conserve School and the Conserve School Trust.

He also served on the President’s Advisory Council of Stevenson University, chaired the advisory board for the Baltimore City campus of the School of Continuing Studies at the Johns Hopkins University, and served on the Baltimore City board of finance.

He taught corporate finance and negotiation at Johns Hopkins and St. Thomas College in Minnesota. He was also a Big Brother volunteer.

Survivors include his wife of 42 years, Bryn Bjella Parchman, former director of the Port Discovery Children’s Museum; two sons, L.J. “Jack” Parchman III, of Mission Hills, Kansas, and Andrew Arley “Andy” Parchman, of Darien, Connecticut; a daughter, Kallan “Kallie” Elizabeth Parchman, of Mexico City; a sister, Leslie Parchman Olson, of Boulder, Colorado; and five grandchildren.
