first non-member of the founding family to become a partner of the company and share in its profits. In 1917, under growing pressure from the other partners in the firm due to his pro-German stance, Henry Goldman resigned. The Sachs family gained full control of the firm until Waddill Catchings joined the company in 1918. By 1928, Catchings was the Goldman partner with the single largest stake in the firm. On December 4, 1928, the firm launched the Goldman Sachs Trading Corp, a closed-end fund. The fund failed during the Stock Market Crash of 1929, amid accusations that Goldman had engaged in share price manipulation and insider trading. Mid-20th century In 1930, the firm ousted Catchings, and Sidney Weinberg assumed the role of senior partner and shifted Goldman's focus away from trading and toward investment banking. Weinberg's actions helped to restore some of Goldman's tarnished reputation. Under Weinberg's leadership, Goldman was the lead advisor on the Ford Motor Company's IPO in 1956, a major coup on Wall Street at the time. Under Weinberg's reign, the firm started an investment research division and a municipal bond department, and it became an early innovator in risk arbitrage. In the 1950s, Gus Levy joined the firm as a securities trader, where two powers fought for supremacy, one from investment banking and one from securities trading. Levy was a pioneer in block trading and the firm established this trend under his guidance. Due to Weinberg's heavy influence, the firm formed an investment banking division in 1956 in an attempt to shift focus off Weinberg. In 1957, the company's headquarters were relocated to 20 Broad Street, New York City. In 1969, Levy took over Weinberg's role as Senior Partner and built Goldman's trading franchise once again. Levy is credited with Goldman's famous philosophy of being "long-term greedy," which implied that as long as money is made over the long term, short-term losses are bearable. At the same time, partners reinvested nearly all of their earnings in the firm. Weinberg remained a senior partner of the firm and died in July of that year. Another financial crisis for the firm occurred in 1970, when the Penn Central Transportation Company went bankrupt with over $80 million in commercial paper outstanding, most of it issued through Goldman Sachs. The bankruptcy was large, and the resulting lawsuits, notably by the SEC, threatened the partnership capital, survival, and reputation of
