After war broke out in Europe in 1939, the demand for quality goods and supplies skyrocketed. Mary Warga, an emissions spectroscopist and physics professor at the University of Pittsburgh, became heavily involved in the war effort and started organizing small meetings on applied spectroscopy that gave rise to what is known today as the Pittsburgh Conference. Meeting attendance grew, and by 1946 the Spectroscopy Society of Pittsburgh (SSP) was born. With Warga as its chairperson, the SSP held its first annual Pittsburgh Conference on Applied Spectroscopy.

The SSP joined the Society for Analytical Chemists of Pittsburgh (SACP) and in February 1950, the first Pittsburgh Conference on Analytical Chemistry and Applied Spectroscopy was held on the 17th floor of the William Penn Hotel in downtown Pittsburgh.

The three-day conference attracted 800 attendees at an admission price of $2 each. Prominent researchers in analytical chemistry included Van Zandt Williams, head of infrared spectroscopy at PerkinElmer, and Arnold Orville Beckman, inventor of the pH meter and founder of Beckman Instruments, which in 1998 became Beckman Coulter.

1957 (Pittsburgh)

The number of attendees had grown steadily over the first few years of the conference, as new technologies emerged. Automation was a popular catchphrase in 1957, with automatic recording being applied to burettes for titrimetry, vacuum microbalances, flow colorimeters and turbidimeters.

Every space within a fiftymile radius of the Penn-Sheraton Hotel was filled to capacity. Debates started to emerge over whether to move to another city and grow even larger, or stay in Pittsburgh and limit the show’s growth.
