Dr. Sarah Elizabeth Stewart was born on August 16, 1905 in Tecalitlán, Jalisco, Mexico. In 1949 she became the first woman to be awarded an MD Degree from Georgetown University School of Medicine.
Following her graduation, she went to NIH to the lab of Dr. Bernice Eddy, where Stewart and Eddy developed an interest in researching viral links to cancer based on the pioneering research of Jonas Salk in developing a vaccine for the virus which caused polio. The Salk vaccine was probably contaminated with a virus – that proved to be simian virus form the Monkey kidney in which the Polio vaccine virus was grown. Stewart and Eddy were credited with discovering the first cancer causing, or Polyomavirus in 1953.
Stewart and Eddy were successful in growing the virus in 1958 and the SE (Stewart-Eddy) polyoma virus is named after them. Stewart was the first to successfully demonstrate that viruses causing cancer could be spread from animal to animal. Stewart and Eddy were nominated several times without success for the Nobel Prize. Dr. Stewart returned to Georgetown to teach in 1971 and then retired to Florida.
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
