Gary B. Meisner is the creator of www.goldennumber.net, a popular website dedicated to the mathematics, prevalence, and design applications of the golden ratio. In 2004, he led the development of his PhiMatrix Golden Ratio Design and Analysis software, which is used by thousands of artists, architects, designers, and photographers in over seventy countries, as well as in cosmetic medical and stock market analysis applications. After earning accounting and MBA degrees from two top business schools, he spent most of his career in CFO/CIO roles with operating units of five Fortune 1000 public companies. Gary is now a self-employed technology/systems consultant conducting ongoing research and collaboration on the golden ratio, and his work has been featured in Da Vinci The Exhibition at the Venetian Hotel in Las Vegas. Providing an online community in which new findings can be shared and discussed, he helps others to appreciate the incredible beauty and design in the world around us and to applying these same principles of design to their own creative works.
