Historical NotesMold for Yagle weights. Yagle weights were invented by Wilkinsburg pharmacist and inventor Louis W. Yagle in the 1940s. Yagle had a pharmacy at Wood and Tioga Street from 1926 to 1969 where, in his basement workshop he invented several useful pharmacy tools including the Yagle apothecary and unit weight systems and the Yagle slide rule that helped pharmacists figure out prescription prices. His first invention in 1946 was the Yagle weight system that helped pharmacists weigh fluid prescriptions. This mold was used by Yagle to make the weights. Yagle, who was born in Homewood and attended Westinghouse High school, graduated from the University of Pittsburgh School of Pharmacy in 1925. During his career as a pharmacist he also taught pharmaceutical mathematics at the University of Pittsburgh. He passed away in 1997 at age 93. In his will he bequeathed $500,000 dollars to Allegheny County to build a senior citizens center.
