August 5, 1928 - September 11, 2015 "It's not the size of the dog in the fight, it's the size of the fight in the dog." Mark Twain Irvin X. Rosen passed away peacefully on September 11, 2015, at his home in Prescott, Arizona, surrounded by his children, family and friends. Irv was 87 years old. Irv was born on August 5, 1928, in St. Louis, MO to Samuel and Fannie Rosen and was one of five siblings. Irv graduated from Garfield High School in Los Angeles, and then went on to earn his Bachelor of Science and a Masters in Business Administration from UCLA, graduating in 1951. Irv served during the Korean War in the United States Marine Corps, stationed at Cherry Point Marine Corps Base, North Carolina and Treasure Island, San Francisco, California, where he built and repaired military radio transmission equipment. In 1953, Irv joined the family business', Rosen's Electrical Equipment Co, and Samuel Rosen & Sons, and became the company's Chief Financial Officer and Managing Partner, until his passing. His keen business sense was instrumental in creating new business lines, including strategic purchasing of commercial property and growing the investment arm of business.
