Before even reading the twitter link I went to Google maps to see where Windber, PA was. The first thing that jumped out to me on the map was Chan Soon-Shiong Medical Center at Windber.

I started digging and found out that it was founded in 1905 as Windber Hospital, funded by Edward J. Berwind, President of the Berwind­White Coal Mining Company. In 2016, the hospital became part of a national non-profit network under Dr. Patrick Soon-Shiong, and renamed Chan Soon-Shiong Medical Center at Windber.

Career:

Soon-Shiong joined UCLA Medical School in 1983 and served on that faculty until 1991,[16][2] as a transplant surgeon.[9] Between 1984 and 1987, he served as an associate investigator at the Center for Ulcer Research and Education.[2] Soon-Shiong performed the first whole-pancreas transplant done at UCLA,[17][18] and he developed and first performed the experimental Type 1 diabetes-treatment known as encapsulated-human-islet transplant, and the "first pig-to-man islet-cell transplant in diabetic patients.

Soon-Shiong purchased Fujisawa, which sold injectable generic drugs, in 1998. He used its revenues to develop Abraxane, which took an existing chemotherapy drug, Taxol, and wrapped it in protein that made it easier to deliver to tumors. He was able to quickly move it through the regulatory process and made his fortune with this medicine.[20] In 1991, Soon-Shiong left UCLA to start a diabetes and cancer biotechnology firm called VivoRx Inc. This led to the founding in 1997 of APP Pharmaceuticals, of which he held 80% of outstanding stock and sold to Fresenius SE for $4.6 billion in July 2008.[21] Soon-Shiong later founded Abraxis BioScience (maker of the drug, Abraxane),[4] a company he sold to Celgene in 2010 in a cash-and-stock deal valued at over $3 billion.[22]

Soon-Shiong founded NantHealth in 2007 to provide fiber-optic, cloud-based data infrastructure to share healthcare information.[23] Soon-Shiong went on to found NantWorks in September 2011, whose mission was "to converge ultra-low power semiconductor technology, supercomputing, high performance, secure advanced networks and augmented intelligence to transform how we work, play, and live."[24][25] It owns a number of technology companies in the fields of healthcare, commerce, digital entertainment as well as a venture capital firm in the healthcare, education, science, and technology sectors.

Investments:

In 2013, Soon-Shiong became an early investor in Zoom, the video conferencing company.[52]

In September 2018, his company NantEnergy announced the development of a zinc air battery with a projected cost of $100 per kilowatt-hour, which is less than one-third the cost of lithium-ion batteries.[57]

In 2019, Soon-Shiong became an investor in Directa Plus, a European-based graphene based technology company, where he owns 28 percent of the company.
