Kathryn Goulding has been involved in classical education for many years, having taught mathematics and logic for two classical Christian schools, and serving for ten years on the board of one of them. She has taught in a variety of settings from elementary school through college. She developed and taught logic workshops for use at the junior high and high school levels, and while teaching high school geometry assembled this book. It is her hope that it will be of use to those wishing to teach or study geometry directly from Euclid's Elements. Kathryn graduated from Bucknell University with a B.S. in Mathematics and earned her M.S. in Mathematics from the University of Florida. She has had a life-long love of Astronomy, enjoys biking and swimming, and is an avid reader of both fiction and non-fiction. She and her husband Tom live in Massachusetts.
