In 1803, at Thomas Jefferson's behest, he tutored Meriwether Lewis in medicine and paleontology to prepare him for the Corps of Discovery's journey west.

American Pharmaceutical Association

Philadelphia, PA · est. 2001

In the fall of 1852, pharmacists from eight states gathered in Philadelphia to found what became the American Pharmaceutical Association, an early attempt to bring order and standards to a trade where the purity of drugs was often anyone's guess. Among the founders was William Proctor, Jr., a Philadelphia druggist and teacher later honored as the "Father of American Pharmacy." Their goal was practical and urgent: to ensure that medicines reaching the public were both safe and honestly made.

Presbyterian Church in the U.S.A.

Philadelphia, PA · est. 1989

In the spring of 1789, delegates gathered at Philadelphia's Second Presbyterian Church for the first General Assembly of the Presbyterian Church in the U.S.A., knitting scattered colonial-era congregations into a single national denomination. The timing was no accident: the young republic was organizing its own federal government that same year, and America's churches were building parallel national structures freed from British ecclesiastical authority. The meetinghouse itself had stood on this ground since 1750.
