(b. Charles County, Md., 1745; d. Charles County, 20 April 1790.), lawyer and judge. The eldest son of Richard and Dorothy Hanson Harrison, little is known of Harrison's early life and legal education. He began law practice in Alexandria, Virginia, where he enjoyed success, numbering among his clients George Washington, with whom he also established a close and lasting friendship. For much of the Revolutionary War he served as Washington's secretary, resigning in March 1781 to accept appointment as chief judge of the General Court of Maryland, a position he held until his death.
Probably because of Harrison's loyal friendship and solid reputation among the legal circles of Maryland, Washington on 24 September 1789 nominated him as one of his original six appointments to the Supreme Court and the Senate confirmed the nomination two days later. Harrison declined the appointment because of failing health, but Washington persuaded him to reconsider and intending to accept the position, Harrison began a journey to New York City on 14 January 1790. One week later a sudden illness forced him to terminate his trip and to decline irrevocably the appointment to the Court. He had also recently declined appointment as chancellor of Maryland.
Harrison's record as chief justice of the General Court of Maryland contains no hints about what he might have done as an associate justice of the United States Supreme Court. The reported cases of his tenure concerned narrow questions of real estate law or other issues that were of no relevance to the significant business of the Supreme Court.
