Hellman assistant president and promoted him to president and chief operating officer on January 1, 1995. Hellman's strong background in corporate finance began with an MBA from Case Western Reserve University. He climbed swiftly through the ranks at Cleveland-based BP America (formerly Standard Oil of Ohio) before joining TRW in 1989 as vice president and treasurer. Among many achievements, he helped to engineer the early 1990s restructuring that saw TRW divest marginal operations, pay down long-term debt, and triple the value of its common stock.
Based manufacturing corporation. Supported by a buoyant national economy, antitrust concerns in the United States, and the nation's leading role in global political and economic affairs. TRW grew rapidly by expanding its traditional commercial businesses around the world and by diversifying into new areas such as electronic components, industrial and commercial tools, energy products, and information systems, among others. During the 1970s and early 1980s, however, a series of shocks and disruptions in the international economythe demise of the gold standard as the basis of Western currencies, two energy crises (each followed by a severe recession), and a prolonged period of high inflation and high interest ratescalled such corporate strategies into question.
Organized and grew. The company descends from several different companies, the oldest of which, Cleveland Cap Screw Company, formed in 1900 to exploit a new electric welding process to make products for the general hardware trade. One of the most vibrant and economically diverse cities in America's industrial heartland, Cleveland provided fertile ground for entrepreneurs such as those who established Cleveland Cap Screw. Electricity was revolutionizing industrial production and residential life.
