Dr. Erik Hockheimer was a general practitioner in the Netherlands before giving up his practice to work with Doctors Without Borders which he did in many countries throughout the world and continues to support an advisor. As a GP he was very involved in the HIV epidemic and that led him to co-author and edit a book on viruses called Virology, published in 1991. While with Doctors Without Borders he continued to work with tropical diseases, HIV, Hepatitis B, and Ebola. He’s retired now but still consults with a number of NGOs particularly around helping refugees.
