Lawyer. Born in Prussia, Frederick's mother died when he was two years old. His father remarried and ruled with an iron hand. The boy ran away at age eight and at age ten left home permanently, never again seeing any of his family. Peddling newspapers and sleeping in vacant buildings, he spent the next seven years crossing the Middle West, working on farms, herding sheep, and getting an occasional term of school. At seventeen his earnestness was rewarded by Judge Epenetus Sears of Tabor, Iowa, who sent him to Tabor College. He received a degree of AB in 1873, and after a brief time in his benefactor's office, was admitted to the Iowa bar. Practicing first in Tabor and Sidney, Iowa, he later settled in Des Moines. He became the attorney for the Wabash Railroad and was active in politics, being instrumental in the election of a Democratic governor, Horace Boise. His railroad practice let him to St. Louis in 1890. There, serving some causes without charge, refusing others at any price, he soon had a reputation for fair dealing such as he had enjoyed in Iowa. In 1908 he was president of the American Bar Association. Named solicitor-general by President Taft in 1910, he accepted the appointment through professional rather than political interest. He served for two years, handling the cases which established the government's right to tax corporation incomes. He then resigned to practice with his sons. In 1914 he represented the United States at the conference sponsored by Argentina, Brazil and Chile to mediate between the United States and Mexico. His most important cases in the course of private practice were those establishing the right of the Associated Press to news as property and securing for the Southwestern Bell Telephone Company the right to earn upon valuation determined by reproduction cost less depreciation. In 1918 he was general counsel for the United States Railway Wage Commission. Republican one election and Democrat the next, he was politically independent and was frequently urged to seek office. He always refused, but in 1909 was appointed chairman of the Board of Freeholders which redrafted the St. Louis charter. He was a founder of the St. Louis Art Museum, president of the public library, a director of the Louisiana Purchase Exposition of 1904 and active in the Missouri Historical Society. He enjoyed public speaking and many of his addresses were published.

ADDITIONAL INFORMATION PROVIDED BY Jean Wilson (48841367): From Wikipedia: President William Howard Taft named Lehmann as United States Solicitor General in 1910. In the Supreme Court of the United States Lehmann established the right to tax corporation incomes. He considered national bank affiliates to be illegal. About Lehmann's oral arguments, Justice Oliver Wendell Holmes, Jr. told Felix Frankfurter that Lehmann was so persuasive "I don't dare decide against Lehmann. You feel as though you're ruling against God."[5]
