In 1933 the prolific inventor Robert Pauli Scherer (1906–1960) invented the rotary die encapsulation process, revolutionizing the soft-gelatin encapsulation field. He founded the R. P. Scherer Corporation to commercialize his invention. R.P. Scherer Corporation was acquired by Cardinal Health, Inc. in 1998, and was a significant part of the Pharmaceutical Technologies & Services segment. Several other businesses were acquired and subsequently spun out of R.P. Scherer Corporation, including Scherer Laboratories. The Pharmaceutical Technologies & Services segment of Cardinal Health was acquired by the Blackstone Group in 2007 and subsequently named Catalent Pharma Solutions.
