Following a prolonged battle with cancer, Carl Henry Arendt, Jr., died on March 4, 2011 in Olympia, Washington.

After earning a degree in physics at Carnegie Mellon in Pittsburgh, Penn., Carl began work at Westinghouse Electric Corporation where he remained his entire career. Following his retirement, Carl and Sheila, his wife of 49 years, moved to Washington to be closer to his son Giles. Active in model railroading for much of his adult life, Arendt became deeply involved in developing small, whimsical layouts in extremely small spaces.

Carl actively promoted the concept of micro layouts which he defined as one that – regardless of scale - occupied a space no larger than four square feet. Carl published several books about small layouts and hosted the Micro Layout Design Gallery, a popular web site ( http://www.carendt.com) that gained a large, world-wide following of hobbyists with whom he developed a close kinship.

Carl’s demeanor exemplified the notion of having fun with model trains. In addition to his wife and son Giles, Mr. Arendt is survived by two other sons, Christopher and Richard Tauson.
