Eli Lilly and Company

History and development

The company was named for its founder, Colonel Eli Lilly, a trained pharmaceutical chemist and a veteran of the American Civil War; biographical accounts note his background and public service during the Civil War era. In the early decades the firm made and marketed a range of patent medicines and ethical pharmaceuticals. Its work on therapeutic insulin in the 1920s contributed to modern diabetes care and established Lilly as a major insulin producer worldwide. The company continued to expand through the 20th century, with growing international sales and a broadening product portfolio before and after World War II.

Lilly develops and markets drugs across multiple therapeutic areas. Historically the company is best known for its role in diabetes care, including early insulin brands such as Iletin and later modern formulations. Diabetes-related research and production remain core activities; corporate and industry reports describe Lilly's long-standing engagement with diabetic treatment and with insulin therapies in particular (insulin).
