Nan Schaffer is a conservationist and internationally recognized expert on the rhinoceros and reproduction. Although her research programs focused on reproductive issues in a variety of mammals, Dr. Schaffer's greatest contributions to science and conservation center on the five species of rhinoceros. In 1998, concerned with the continued decline of these critically endangered species, Dr. Schaffer refocused her efforts and founded SOS Rhino, an international non-profit organization focused on saving rhinoceroses in their natural habitats. SOS Rhino's community-based conservation programs built on the capacity of all stakeholders to conserve by raising local awareness and promoting protection of habitats and animals. In addition to her contributions to science and conservation, Dr. Schaffer is also a philanthropist and activist in the LGBT community. She was the first woman invited to join the Board of IMPACT, the predecessor to Equality Illinois, the state's oldest and largest LGBT political action committee. In 1985 she co-founded Outlines, one of the first lesbian newspapers in the Midwest, which became The Windy City Times, the oldest and only surviving LGBT newspaper in Chicago. In addition to her political and publishing efforts, Dr. Schaffer supported numerous LGBT organizations with her time, wisdom and financial resources, and in 2004, she was inducted into the Chicago Gay & Lesbian Hall of Fame. In her retirement, Dr. Schaffer has continued her philanthropy, activism and conservation efforts. She serves as a governing member of the Chicago Zoological Society's Board of Trustees and continues to consult with Malaysian government officials and leaders of rhinoceros conservation programs.
