Brown & Heim Inc., established in 1933 by Edward Brown and Arthur Heim, specializes in electrical construction services within the Baltimore-Washington area. The company was initially focused on converting DC-powered buildings to AC power during its early years. As World War II unfolded, Brown & Heim expanded rapidly to meet the increased demand for construction services in shipyards, employing up to 900 electricians to retrofit cargo ships with advanced power distribution systems.
Following the war, the leadership transitioned to J. Harold Cornelius, Charles B. Major, and Baldwin E. Dorsch, who leveraged their government connections to establish enduring partnerships, notably with Northrop Grumman, formerly part of Westinghouse Electronic Systems. The company has since diversified its portfolio, serving commercial, industrial, institutional, and hospital sectors while maintaining strong ties with government facilities.
In the 1990s, the leadership saw another transformation under James H. Cornelius, Raymond Miller, and Emerson Shiloh, whose expert knowledge propelled Brown & Heim to its current standing as a reputable entity in electrical construction. The firm averages $20 million in annual revenue, employing 14 skilled staff who provide a range of services, including estimating, engineering, administrative support, and project management. The company’s mission centers on delivering exceptional service through value engineering and technical solutions, prioritizing quality and customer satisfaction. This commitment has fostered long-lasting relationships that extend beyond project completion, cementing Brown & Heim’s legacy in the electrical construction industry.
