Court. He actively sought the appointment, writing to Foraker to urge the governor to press his case, while stating to others it was unlikely he would get it. Instead, in 1890, Harrison appointed him Solicitor General of the United States. When Taft arrived in Washington in February 1890, the office had been vacant for two months, with the work piling up. He worked to eliminate the backlog, while simultaneously educating himself on federal law and procedure he had not needed as an Ohio state judge. New York Senator William M. Evarts, a former Secretary of State, had been a classmate of Alphonso Taft at Yale. Evarts called to see his friend's son as soon as Taft took office, and William and Nellie Taft were launched into Washington society. Nellie Taft was ambitious for herself and her husband, and was annoyed when the people he socialized with most were mainly Supreme Court justices, rather than the arbiters of Washington society such as Theodore Roosevelt, John Hay, Henry Cabot Lodge and their wives. In 1891, Taft introduced a new policy: confession of error, by which the U.S. government would concede a case in the Supreme Court that it had won in the court below but that the solicitor general thought it should have lost. At Taft's request, the Supreme Court reversed a murder conviction that Taft said had been based on inadmissible evidence. The policy continues to this day. Although Taft was successful as Solicitor General, winning 15 of the 18 cases he argued before the Supreme Court, he was glad when in March 1891, the United States Congress created a new judgeship for each of the United States Courts of Appeal and Harrison appointed him to the Sixth Circuit, based in Cincinnati. In March 1892, Taft resigned as Solicitor General to resume his judicial career. Federal judge Taft's federal judgeship was a lifetime appointment, and one from which promotion to the Supreme Court might come. Taft's older half-brother Charles, successful in business, supplemented Taft's government salary, allowing William and Nellie Taft and their family to live in comfort. Taft's duties involved hearing trials in the circuit, which included Ohio, Michigan, Kentucky, and Tennessee, and participating with Supreme Court Justice John Marshall Harlan, the circuit justice, and judges of the Sixth Circuit in hearing appeals. Taft spent these years, from 1892 to 1900, in personal and professional contentment. According to historian Louis
