Nick Enge graduated with an M.S. and B.S. from Stanford University in 2012. Since then, he has been researching, reconstructing, and teaching social dances from the 19th century to present. With the help of his wife and dance partner Melissa, he maintains the Library of Dance, a digital repository of social dance knowledge which includes a bibliography of over 6,700 historical dance manuals (with more than 2,100 available as free downloads), and a collection of over 1,800 demo videos of social dance variations. In addition to researching the dances themselves, he also researches the benefits of dancing, which are detailed in his book, Waltzing: A Manual for Dancing and Living, co-authored with Richard Powers, his colleague at Stanford. He is also the co-author of two other books on dancing, Cross-Step Waltz: A Dancer's Guide, and The Book of Mixers: 100 Easy-Teach Dances for Getting Acquainted.
