Pfizer Inc: Evolving to meet the needs of a changing society

Since Pfizer was founded by cousins Charles Pfizer and Charles Erhart in 1849, our pharmaceutical company has remained dedicated to discovering and developing new, and better, ways to treat and prevent disease and improve the health and quality of life for people around the world. From the miracle of penicillin to the patient support program we’ve developed along with CHANTIX™, a prescription medicine to help people quit smoking, we focus on finding answers to the biggest health challenges of the times. We invite you to explore our rich history and see how we have continually evolved our organization to keep pace with the needs and expectations of our stakeholders and society as a whole.
