Summary
Thomas William Lamont Jr. was a prominent American banker who lived from September 30, 1870, to February 2, 1948. As a leading figure, eventually becoming chairman of J.P. Morgan and Co., he operated within the speculative financial environment that characterized the era leading up to the Stock Market Crash of 1929. This period, as highlighted in the related document, was marked by a significant expansion of leverage, a lack of regulation, and the rise of consumer credit, with other banks like National City heavily lending to speculators. While not directly named in the discussion of the crash itself, Lamont's influential position in the banking industry meant he played a crucial role in shaping U.S. economic policy and financial stability during a time of immense financial transformation and eventual crisis. His career also included significant international financial negotiations, such as chairing the International Committee of Bankers on Mexico.

- Celebrating 150 Years Since the Birth of Thomas W. Lamont
Armbruster estimates that Lamont was probably one of the 100 wealthiest people in the U.S. at the time. He and his wife, their four children, and many grandchildren enjoyed the luxurious estate in Palisades, where they would go hiking through the woods and cruising up the river on their yacht. The family made generous donations to Harvard and Exeter, as well as England’s Canterbury Cathedral. Lamont also supported several women’s causes, including women’s suffrage and women’s colleges. [...] Thomas W. Lamont died in Boca Grande, Florida, in 1948. You can learn more about his life in the video below, narrated by Armbruster. After Lamont’s death, his widow, Florence Corliss Lamont, an alumna of Columbia University, donated the property to the university in her husband’s memory. Although the gift was unrestricted, she was reportedly pleased with the university’s plans to make it into a center of geological research, and assured that “the world [would] benefit.” [...] The company bailout earned Lamont an inroad into the banking industry. He worked his way up through the Bankers Trust, the First National Bank, and J.P. Morgan and Co, where he would eventually become chairman of its board of directors. From these positions of power, he helped to establish U.S. economic policy and financial stability in many countries.
