United Therapeutics

An Electric Helicopter Arrives

Martine Rothblatt is not your typical person. She is the founder of Sirius satellite radio and vehicle navigation company GeoStar. When her daughter was diagnosed with a rare life-threatening form of pulmonary hypertension, Rothblatt formed United Therapeutics to market medication for others suffering from the same disease. Because pulmonary hypertension often requires a lung transplant, she next created a division of her drug company that focuses on developing artificial and transplantable lungs from pig genetics.
