Bristol-Myers Squibb Company
A biopharmaceutical company that discovers and sells medicines for cancer, heart, immune, and brain conditions, with well-known brands like the immunotherapy Opdivo, the blood thinner Eliquis, and the cell therapy Breyanzi. It was formed in 1989 when two old American drugmakers merged: Bristol-Myers, started in 1887 by two college friends who bought a struggling New York firm, and Squibb, founded in 1858 by a doctor who supplied the Union Army during the Civil War. A fun early hit for the Bristol-Myers side was Sal Hepatica, a mineral-salt laxative meant to mimic natural mineral waters.
