Ingersoll admitted to the bar in Philadelphia in 1773. After his return to America, a friend of the fam- ily, Joseph Reed, president of the newly created supreme executive council of Pennsylvania, in- vited him to look after the interest of Reed's clients at Philadelphia. With this auspicious be- ginning as a member of the Philadelphia bar, he soon became one of the most distinguished law- yers of the city in an age when Philadelphia boasted the finest legal talent of the country. He was attorney for Stephen Girard, merchant, and Senator William Blount, against whom impeach- ment proceedings were brought in 1797. He was admitted in 1791 to the bar of the Supreme Court of the United States. During the next year he was counsel for Georgia in the case of Chisholm vs. Georgia (2 Dallas, 419), the first of a num- ber of cases argued by him involving various phases of federal relations. In opposition to Alexander Hamilton, in 1796 he was an attorney in the first case involving the question of the constitutionality of an act of Congress (Hylton vs. United States, 3 Dallas, 171). He was also counsel in cases connected with foreign relations as affected by constitutional law and the juris- diction of the courts, notably Mcllvaine vs. Coxe's Lessee (2 Cranch, 280, and 4 Cranch, 209). Meanwhile Ingersoll had held many public of- fices. In 1780 he was elected a member of the Continental Congress and by 1785 he was taking an active part in the agitation for revising or supplanting the Articles of Confederation. He was a delegate to the Federal Convention of 1787, but took little part in its deliberations. William Pierce said of him: "Mr. Ingersol speaks well, and comprehends his subject fully. There is a modesty in his character that keeps him back" (Max Farrand, The Records of the Fed- eral Convention of 1787, 1911, III, 91). In local politics he was a member of the Philadelphia Common Council in 1789 and from 1798 to 1801 he was city solicitor. From 1790 to 1799 and again from 1811 to 1817 he was attorney general of Pennsylvania; for a short time (1800-01) he was United States district attorney for Pennsyl- vania; and in 1811 he was nominated by Penn- sylvania Federalists for the vice-presidency. From March 1821 until his death in 1822 he was presiding judge of the district court for the city and county of Philadelphia. In politics he was at first inclined toward democratic views but the events of 1801 seem to have been considered by him "the great subversion/' and thereafter in so far as he took part in politics it was as a Fed- eralist. His main interest, however, was always the law. Of his three surviving children, one Ingersoll was Charles Jared Ingersoll [#.£/.]. Another son, Joseph Reed Ingersoll, well known at the Phila- delphia bar, was briefly minister to England in Fillmore's administration. § [For the early life of Jared Ingersoll, see the life of his father, L.

He was descended from Richard In- gersoll, who settled in Salem, Mass., in 1629. His father, John Ingersoll, born in Vermont and a graduate of Middlebury College, was a clergy- man who served in turn many Congregational and Presbyterian churches; in the manse of one of these, at Dresden, N. Y., Robert Green Inger- soll was born. His mother, Mary, daughter of Judge Robert Livingston, was no more than an ideal of sentiment to Robert, since she died in his infancy. John Ingersoll, orthodox in his be- lief, was unable to steer his son into the channels of mental regularity. While the latter was yet a boy the family moved to Ohio, to Wisconsin, and then to Illinois, where at the age of twenty- one he was admitted to the bar at Shawneetown. He spoke often in terms of respect for his father and veneration for his mother, but he rarely re- lated the details of a childhood that seems to have been harsh and narrow. He was essentially a self-made man, finding companionship in his brother, Ebon Clark Ingersoll, with whom he practised law, later a representative in Congress from Illinois (1864-71), and in his wife, Eva Amelia Parker, as free a thinker as himself, whom he married on Feb. 13, 1862. He had two daughters who, with grand-children and rela- tives, made him in his later years the center of a patriarchal group. Ingersoll moved from Shawneetown to Peoria in 1857 and soon became a leader at the bar and a distinguished pleader before juries. His talents brought him the post of attorney-general of Illi- nois, 1867-69; but before he reached that dignity his career was interrupted by military service. He assisted in raising and became colonel of the nth Illinois volunteer cavalry regiment, which was mustered into Federal service on Dec. 20, 1861. His command saw duty in the Tennessee Valley campaign, at Shiloh and at Corinth, and
