About

In 2016, we celebrated our 125th anniversary – 125 years of being guided by the conviction that great medicines change the world.

Since we began in 1891 in the United States, our researchers have helped to find new ways to treat and prevent illness – including the discovery of vitamin B1; the first measles vaccine; cold remedies and antacids; and the first statins to treat high cholesterol. Our scientists have also helped develop many products to improve animal health, including vaccines and antibiotics.
