On May 28, 2010, Frank Muller, age 91, quietly slipped away to join our heavenly father, Jesus Christ. Frank was born in Havre de Grace, MD, on December 26, 1918 He graduated from John Hopkins University in 1939 where he majored in electrical engineering. Upon graduating from Hopkins, he went to work for the G. L. Martin Co. in the design division on a wide variety of projects including the B-26 bomber and other military projects. He met the love of his life, Jane, while working at the Martin Co. and they were married May 10, 1947, a marriage lasting until his passing. He and his growing family lived in Glen Arm, MD. As their children grew, family life centered on school activities, scouting, summer swimming lessons, and a fulfilling church life. He was transferred to Denver in 1973 and retired from the Martin-Marietta Co. in 1984 after 49 years of service. Retirement proved to be fun and rewarding as he and Jane became increasingly involved with the homeless shelter at the First Presbyterian Church in down-town Denver. He and Jane also were involved as volunteers for 'River Rats', an organization sponsored by the Denver Presbytery and the Denver Home of Neighborly Services that gave inner city kids a chance to go camping and rafting on the upper Colorado River. These service opportunities were expressions of God's love in all of life and all who participated were made better by it. Their retirement life was an extension of their faith and love of God. In 1995, Frank and Jane moved to Fort Collins to be near family. Soon after, they had their dream home built in a neighborhood they truly loved. The neighbors turned out to be the best anywhere. Frank is survived by his wife, Jane; son Leslie of Alcoa, TN, wife Margaret and children, Leslie and Lauren; daughters Meredith Muller of Sammamish, WA, husband Michael Goodwin, and children, Matthew, wife Whitney, and Meryl; Sharon Colson of Gunnison, CO, and son John David; Robin Langowski of Ft. Collins, CO, husband Paul, and children Cassidy and Nicholas; Merle Muller of Palmer, AK; and, Marianne Muller-Westort of Ft. Collins, husband Sr. Mstr. Sgt. Tom Westort, USAF (ret.) In addition to his parents, Frank was preceded in death by his only brother, Harry Muller, of Kinsale, VA. A memorial service for Frank will be held on Saturday, June 6, 2010, at 1:00 p.m., at Westminster Presbyterian Church, 1709 W. Elizabeth St, Ft. Collins, CO.
