Some of Louis’ ancestors were Vikings, both Danes and Celts, and we always saw him that way! He loved the outdoors, loved water with kayaking on the rivers and boating on the lakes, sailed around the west coast in his private plane and loved skiing, mountain biking, bow and gun hunting and exploring. He was a volunteer fireman 1970-77 and reached the three-gallon level in blood donations. That all has come to an end. Louis died August 5, in Yellow Springs Ohio, from heart failure and pancreatic cancer — the same illness that took his father at the same age.
Louis was born August 23, 1943, in Trona, in the California desert. He graduated with honors from Trona High School in 1961, after being very active in the marching band, football, basketball and track – Louis set a school record for the 880 yard sprint. When asked what had been a memorable event in his life, he answered it was when his high school basketball team “won the State championship!”
Louis went on to receive a Bachelor of Science degree in Electrical Engineering from California State Polytechnic University in 1966. At one time during that period, all three Sims brothers were attending Cal Poly. After graduation, Louis married Carol Ford in Trona and they moved to Seattle where Louis worked on Minuteman missiles with Boeing Aircraft; he was excused from the Vietnam draft because he was a rocket scientist. He received a Master’s in Electronic Engineering from the University of Washington.
When the missile contract ended, Louis found new work with Keytronic, a startup computer company in Spokane. He designed and patented a capacitive switch for computer keyboards for them, which led to $100 million per year in sales. In 1977, Louis became vice-president of engineering for ISC Systems and directed development of on-line cluster terminal systems for banks. In 1986, Louis moved to Output Technology Corporation, which produced high speed-impact printers, where he launched three new products and won a government contract worth $50 million. He was president and CEO 1993-2000 and increased sales from $4 million to over $30 million per year and sold the printers in several countries around the world.
Louis is survived by his children Jenniffer, Jilliann, Evan, Hayley, and nieces Tiffany and Serrina Sims and his wife Mary Sims and her daughters Valerie, Alisa and Demi Kosheleff. He is also survived by his brother Richard and his wife Cindy. Louis’s ashes will be scattered in Yellow Springs and on a mountain near Spokane.
