William N. Jackson, a decorated World War II veteran and retired Internal Revenue Service group supervisor who assisted in the criminal investigation of 1970s political corruption cases, died at Sinai Hospital on Sunday after falling at his home. He was 86 and lived in North Baltimore.
Born at his parents' Montford Avenue home in Baltimore, he was a 1944 graduate of Patterson Park High School. Family members said he was drafted into the Army that summer and sailed to Europe in early 1945. He fought in the Battle of the Bulge and was wounded at Dortmund, Germany, in April 1945. He was awarded the Purple Heart, Bronze Star and Combat Infantry Badge.
After the war, Mr. Jackson earned a history degree at Washington College and married his high school sweetheart, Geraldine Anne Fisher, in June 1950.
He joined the IRS in the early 1950s and worked in collections and audits. He became a Criminal Investigation Division special agent in Baltimore and then group supervisor in his division. He worked on the corruption cases of Baltimore County Executive Dale Anderson and Spiro T. Agnew, who had been governor of Maryland and became vice president under Richard M. Nixon.
Mr. Jackson was also assigned to investigate and report to the House Judiciary Committee on the tax evasion portion of the impeachment counts brought against President Nixon, family members said.
In 1978, Mr. Jackson was assigned to Washington as a special assistant to the Internal Revenue Service commissioner.
"He was a straight shooter and told you exactly what he thought," said his son, Paul Norris Jackson of Hunt Valley.
After retiring in 1981, he worked with local attorneys as a consultant on tax-related cases.
Mr. Jackson traveled extensively in the U.S. and Europe. He also was a movie buff, and read history and crime fiction. He enjoyed a single-malt Scotch at night.
A Mass of Christian burial will be held at 1:30 p.m. Friday at Immaculate Conception Roman Catholic Church, 200 Ware Ave. in Towson, where he was a member.
In addition to his wife of nearly 62 years and his son, survivors include another son, Philip Senan Jackson of Baltimore; four grandchildren; and a great-grandson.
