David L. Begley, 58, died Monday, Jan. 18, 2010, in his home in Longmont, Colo.
He was born Oct. 12, 1951, in Hannibal, the son of Richard (Dick) Lawrence and Mildred Elwood Begley.
Survivors include a son, Tristan Begley and wife, Cynthia; and two daughters, Venessa and Audra Begley, all in Boulder, Colo.; his mother, Mildred Begley, Palmyra; and a brother, Phillip L. Begley and wife, Monica, in Quincy, Ill.
He was preceded in death by his father.
Mr. Begley was the owner/president of David L. Begley, LLC and provided research, analysis and consulting services in the field of aerospace, lasers and optical communication. Previously he served as the vice president of strategic management for Ball Aerospace & Technologies Corp., Boulder, Colo.; senior technical specialist for McDonnell Douglas Astronautics Co., St. Louis; professor – Electrical Engineering Dept., SIU-Carbondale, Ill.; development engineer for John Deere Product Engineering Center, Waterloo, Iowa; and was a graduate assistant at the  University of Missouri-Rolla, Rolla.
He was a 1969 graduate of Palmyra High School, a 1971 graduate of Hannibal-LaGrange College and received his bachelor, master and doctor degrees in electrical engineering at the University of Missouri-Rolla.
Mr. Begley was the editor of five books and the author of many articles in professional specialty trade journals in addition to speaking and lecturing at numerous conferences and symposiums during his career.
Throughout his life, he was involved in a variety of community services through his children’s schools, youth organizations, colleges and universities, such as being a group leader in the Boy Scouts and YMCA Parent Youth Programs, just to name a few.
Besides being a devoted father and involved in all aspects of his children’s lives, his main hobbies were hiking, fishing, snow skiing, playing the guitar and amateur radio.
A brilliant man who had a gift for understanding, trouble shooting and fixing any type of electrical or mechanical devices, he found joy, whether it be in launching a rocket into space, or rebuilding a carburetor for a tractor on the family farm.
His contributions to biotechnology, national defense and other sciences will live on long after his passing. But of his multitude of achievements, none were more rewarding to him than his three children. As a father, son, brother, friend and colleague, his presence in our lives will be sorely missed.
Private memorial services celebrating his life will be held in the mountains of Colorado in the spring and another in Palmyra at a date yet to be determined.
