Robert H. Bushnell died peacefully on January 28th, 2018. He is survived by his wife Martha, his daughter Helen, his son Orson, and his brother Bill. He was 93. Robert was born and raised in Wooster, OH, and received Bachelors and Masters Degrees from Ohio State in physics and electrical engineering after serving in the Navy in WWII as a Radar operator. He then spent several years in the commercial sector during which time he received his first patents, including one for airplane collision avoidance. He then went back to school at the University of Wisconsin to study for his PhD in Meteorology. Following his final degree, Robert moved to Colorado where much of his career would be devoted to public service. He worked at NCAR when it was first created, focusing on thunderstorms. He then worked as a consultant in the burgeoning solar industry. In addition to building the second solar collector in Boulder county, he studied ways to improve collector designs and the thermal response of buildings. Finally he worked at NOAA where he made sure that the contractors who make our weather satellites did their jobs correctly and efficiently. Throughout this time, he worked to convert the US to the metric system. The Memorial Service for Robert H. Bushnell will be at the Unitarian, Universalist Church in Boulder at 5001 Pennsylvania Avenue, Boulder, CO 80303 on Sunday, February 18 at 1pm followed by a small meal.
