'Bernhard Joos' (18 December 1899 Schaffhausen, Switzerland - 8 June 1990 Paradiso, Switzerland), was the son of Dr. Bernhard Joos, and Olga Sturzenegger.
He attained a PhD in chemistry at the University of Zurich in 1925, and was an assistant of Paul Karrer, who won the Nobel Prize in Chemistry in 1937. After a stay in the U.S., he returned to Switzerland in 1932 and started his own laboratory where he discovered Pyridazil, his first medicine.
In 1936 he created the pharmaceutical company Cilag (Chemical Industrial Laboratory AG). He left the company in 1949, and in 1959 Cilag was acquired by the US company Johnson & Johnson.
