Maryland's comptrollers were a diverse group from all parts of the Old Line State. Sixteen were from eight counties on the Eastern Shore, while 14 were from seven counties and Baltimore City on the Western Shore. The two youngest were 28 years old when they entered office while the oldest was 79. Two served in office until they reached 85 years of age.
Twenty-five have been Democrats and only two were Republicans while several before and during the Civil War were Whigs, Know-Nothings and Unionists. Several served in the Civil War on both sides and a few served in World Wars I and II.
A half-dozen were governors, many were in the General Assembly, and several held national office. Eighteen were lawyers, three were physicians and the rest have been newspaper editors, farmers, bankers and accountants, while one was a teacher and another a miner. Quite a few were influential businessmen in their local communities. Seven served a year or less and one served for 39 years. In fact, three individuals accounted for three-quarters of the last century. Three died while they were in office.
