Hillegas Bureau of Standards in 1908, and held the posi- tion until his death. Under him the chemistry division increased greatly in the scope of its work.

He was active in the American Chemical Society; he served on its committee on coal analysis, and for years was chairman of the supervisory committee on stand- ard methods of analysis.

His father, an emigrant from the Palatinate, was a naturalized citizen of Pennsylvania, a prosperous merchant, and a respected leader of the German population. His son was given the best education afforded at the time by the parochial schools and academies of Philadelphia, and at an early age entered his father's counting-room. When he was twenty- one, upon his father's death, he became manager of the business and one of the administrators of his father's estate. Later he invested in sugar refining and in the manufacture of iron and amassed a considerable fortune. His first pub- lic service was that rendered in 1762 as a com- Hillegas missioner to locate and erect Fort Mifflin, Pa. He was a member of the provincial Assembly of Pennsylvania, 1765-75, and during this time was a member of the commission to audit and settle the accounts of the general land office and other public accounts. He was a member of the board of commissioners to improve the navigation of the Delaware River in 1771; a member of the committee of observation for Philadelphia, 1774; and on June 30,1775, was appointed treasurer of the Pennsylvania committee of safety. A month later, July 29, 1775, Hillegas and George Clymer were made joint treasurers of the united colo- nies, by action of the Continental Congress, being styled "Continental Treasurers." Mean- while, on May 30, 1776, he assumed the addi- tional duties of treasurer of the Province of Pennsylvania. When Clymer took his seat in Congress, Hillegas was made sole Continental Treasurer, Aug. 6, 1776, and on Sept. 6, 1777, he was appointed treasurer of the United States of America. He continued to serve until Sept ii, 1789, after the Treasury Department had been established by act of Congress, under the federal Constitution. During the Revolution he contributed a large part of his fortune, by gift or loan, to the support of the army, and in 1781 he was one of the first subscribers to the Bank of North America. By direction of the Penn- sylvania General Assembly he compiled and pub- lished in 1782 Volume I of Journals of the House of Representatives of the Commonwealth of Pennsylvania, covering the period between Nov. 28, 1776, and Oct. 2, 1781. Apparently this task stimulated his interest in the preservation of his- torical material, for in a letter of Aug. 20, 1781, to the governor of New Hampshire he suggested "the propriety of each legislature in the Union adopting measures similar to those taken by this state for the above purpose" (Egle, post). Upon the discovery of anthracite coal in Pennsylvania about the first of the year 1792, Hillegas with some others formed an association called the Le- high Coal Mining Company which purchased several thousand acres from the Commonwealth of Pennsylvania but probably never mined any great quantity of coal. He was an alderman of Philadelphia from 1793 until the year of his death, and an associate justice of the mayor's court. He was elected a member of the Ameri- can Philosophical Society, Apr. 8,1768. At one time he was a vestryman of Christ Church. "Hillegas ... is a great musician," wrote John Adams, "talks perpetually of the forte and piano, of Handel, etc. and songs and tunes. He plays upon the fiddle" (The Works of John Adams, vol. II, 1850, p. 429). On May 10,1753, he mar-
