[sumonasumonakha.tu1]

Before we dive into the specifics of Pfizer’s business model, including revenue streams, customer segments, and value propositions, let’s briefly review Pfizer’s history and who owns it to understand how Pfizer has become a leader in the pharmaceutical industry, from its humble beginnings in New York City to its current status as a global company.


Pfizer is one of the world's leading pharmaceutical companies, with a long and storied history student data dating back more than 170 years. The company was founded in 1849 by Charles Pfizer and Charles F. Erhart, two German immigrants who initially produced chemical compounds in a rented building in Brooklyn, New York. Despite financial setbacks and competition from larger, more established companies, Pfizer became a leader in the pharmaceutical industry in the early 1900s

In 1900, William H. Erhart, son of Charles Erhart, joined the company as vice president. He later served as chairman of the board from 1929 to 1940, and under his leadership, Pfizer continued to expand its product line and increase its manufacturing capabilities.

During World War II, Pfizer produced penicillin, a life-saving antibiotic that helped save countless lives on the battlefield. After the war, Pfizer focused on developing new antibiotics and other drugs to treat a variety of conditions.

Pfizer, then a brick-and-mortar company, has since focused on topping the charts and making a name for itself in the healthcare industry.
