Hans J. Wehrli passed away on February 20, 2020. He is survived by his wife of 64 years, Lisette (Leichti) Wehrli, and his children Nicole Wampfler, Gregory Wehrli, and Linette LaMountian, as well as his 7 grandchildren (Jake Wampfler, Carlene Wampfler, Mathew LaMountain, Christopher LaMountain, Peter LaMountain, Jackson Wehrli, Michael Wehrli). Hans was a long time resident of Valhalla, NY and more recently a resident of Wilton, CT. Hans, born in Aarau, Switzerland, on April 25, 1926, (93 years old) was the youngest of 5 children. His childhood was not easy especially during the war time however he was never one to sit still and was always curious. One time, around the age of 10, the doctor came to the house. Hans had to understand the working of the doctor’s bicycle so he completely took the bike apart while the doctor was inside. Hans had several hobbies that he was passionate about - he would read every minute of the day – newspapers, art books, detective novels. You could always find him in a corner on the deck at the beach house in Westhampton reading something. Hans enjoyed camping across the United States and Canada with his family. Usually those trips would conveniently coincide with a destination where the ASPRS convention was being held or customers were in the nearby town. Hans loved to collect and trade oriental prayer rugs and Meissen porcelain in his spare time. He often purchased items in the US and would bring it to Switzerland to sell. In Switzerland, among the porcelain collectors, he was known as the “Meissen King”. Hans enjoyed cooking and he was very good at it. He usually referred to how he would watch his mother and that is how he learned how to cook. He would make anything and everything from kidneys to roasts to poached fish to flan to strawberry souflee. Of course, Hans had to become a sommelier to serve the perfect wine along with the meals. His career was very exciting and fulfilling. Hans came to the United States in 1953 to expand Kern Instruments Inc., a subsidiary of Kern & Co. AG, Aarau, Switzerland. Initially, the focus of his assignment was in surveying instrumentation, including adaptation of such instruments for the optical tooling industry, ranging in applications from alignment of paper machines to sophisticated guidance systems in the aerospace industry. Later, under Hans’s leadership and guidance, Kern entered the photogrammetric market (map making) with his instrumentation concept, design and sales. Hans was considered a visionary in his field as demonstrated by his early understanding of the benefit of electronics to improve productivity. Some unique projects were in 1969 having Kern optical lenses accompany the moon landing of Apollo 11 where these lenses were used in the craft’s acquisition cameras which filmed the tests of reactions of men and materials in space; the first Industrial Measurement System used for the alignment of the magnets of the Stanford Linear Collider. In 1988, Hans received the ASPRS Fairchild Award established to recognize someone who demonstrated outstanding efforts and influence in the development of the art of aerial photogrammetry in the United States. Even after retiring in 1988, Hans continued to work until his late 80s, designing and bringing to market photogrammetric instrumentation through Wehrli & Associates.
