Gregory Hammond Olsen (born April 20, 1945) is an American entrepreneur, engineer and scientist who, in October 2005, became the third private citizen to make a self-funded trip to the International Space Station with the company Space Adventures. Olsen was the co-founder and chairman of Sensors Unlimited Inc., a company developing optoelectronic devices such as sensitive near-infrared (NIR) and shortwave-infrared (SWIR) cameras. One of Sensors Unlimited's major customers is NASA. Currently, Olsen is President of GHO Ventures, LLC, in Princeton, New Jersey, where he manages his angel investments, South African winery, Montana ranch, Manhattan and Miami real estate, and performs numerous speaking engagements to encourage children – especially minority and female children – to consider careers in science or engineering. He also is a physics professor at Rider University. Early life and education Olsen, born in Brooklyn, New York, was the son of an IBEW Local 3 electrician. His mother was a school teacher. He grew up in Bay Ridge and graduated from Ridgefield Park High School, Ridgefield Park, New Jersey in 1962. Olsen initially wanted to be a baseball player but realised from local little league how tough the standard was. Olsen was inspired by his father to become an electrician, always having the education at home to fix things in-house instead of calling a repairman. After being written off as a failure by teachers due to poor grades in high school, Olsen planned to join the United States Army until he was counseled to try college for several months. Through an IBEW Local 3 scholarship, Olsen attempted college, kept his grades high, and graduated magna cum laude with multiple degrees from Fairleigh Dickinson University. He later graduated with a PhD in materials science from the University of Virginia. He has two daughters, Kimberly and Krista, and six grandchildren: Justin Dibsie, Carter Dibsie, Danielle Dibsie, Romina Lapadula, Athina Lapadula, and Oriana Lapadula. Business career Olsen admits to little business training and believes that for companies making less than 100 million (the smaller companies as he calls them) that success is based more on “intuition, instinct and hard work.” He does credit his success to his graduate science training. “Two of my start-up companies are from the fields I trained in. For instance, my first company EPITAXX (a supplier of optical detectors and receivers for fiber optic telecommunications and cable television networks) relied on my knowledge of physics and material
