Harrison had four Supreme Court appointments: David J. Brewer, Henry B. Brown, George Shiras, and Howell E. Jackson. Brewer was the nephew of former U.S. Supreme Court Justice Stephen Field and a strong conservative. He served for more than twenty years on the Court. Brown served for fifteen years. He dissented in the Supreme Court’s decision in Pollock v. Farmers’ Loan and Trust Co. (1895), where the majority of the Court invalidated a federal income tax. Shiras served for eleven years and often voted for big business interests during his tenure. Jackson, from Tennessee, only served two years. His appointment was a bit unusual in that Harrison, a Republican, nominated Jackson, a Democrat, to the bench. Jackson had distinguished himself as a federal appeals court judge.
