Dr. Martine Alisa Rothblatt, J.D., M.B.A., Ph.D., is an American businesswoman, the self-made billionaire Founder and Executive Chairman of United Therapeutics (NASDAQ: UTHR), a major biotechnology and pharmaceutical company. Her career is rooted in law, communications technology, and serial entrepreneurial audacity.

Rothblatt holds an MBA and a J.D. Law degree from UCLA (1981). Her pivotal entrepreneurial move was founding Sirius XM Satellite Radio in 1990 (originally Sirius Satellite Radio). Her philosophy centers on technological disruption (in satellite communications and biomedicine) and humanitarian purpose (curing diseases). She transitioned gender in 1994, becoming one of the highest-profile transgender CEOs in the world.

• United Therapeutics (Founder & Executive Chairman): The core publicly traded asset, a major biotech firm focused on pulmonary arterial hypertension (PAH) and organ manufacturing (using pig lungs).
• Sirius XM (Founder): The global satellite radio company she founded (leaving in 1994).
• Technological Pioneer: She is the pioneer of GeoStar (a global satellite navigation system) and holds a Ph.D. in Medical Ethics (reflecting her commitment to bio-pharma).
• Personal Mission: Her founding of United Therapeutics was inspired by her daughter's diagnosis with PAH.

Dr. Martine Rothblatt's strategic genius was her commitment to high-risk, high-reward technological disruption. She founded Sirius XM Satellite Radio in 1990 (leaving before its major success) and then pivoted to biotechnology in 1996, founding United Therapeutics. The company's mission was directly driven by her daughter's diagnosis with PAH—a commitment to curing the disease.

Her structural contribution is immense: pioneering a new generation of PAH treatments and advancing the field of xenotransplantation (using pig organs for human transplant). Her wealth is secured by her long-term equity stake in the publicly traded company and the colossal, stable, and continuous profitability of the specialty pharmaceutical sector.

Dr. Martine Rothblatt's social impact is massive and humanitarian, tied to United Therapeutics' role in developing life-saving PAH treatments and advancing organ transplantation technology. Her personal story (her gender transition in 1994) is a major contribution to LGBTQ+ visibility in the corporate world. Her Terasem Movement Foundation promotes cryonics and transhumanism.

Her structural contribution is tied to her belief in technological audacity and humanitarian purpose as the core drivers of business innovation.

Dr. Martine Rothblatt maintains the professional, composed style of a technology executive. Her attire is consistently formal and high-quality, favoring tailored suits. Her aesthetic reflects serious authority and intellectual depth, typical of a pioneer in the specialized biotech sector.

Residing in Satellite Beach, Florida, her luxury is the immense security and financial reward derived from her multi-billion dollar fortune. Her life is dedicated to biotechnology innovation, legal advocacy, and transhumanism research.
