Some notable quotes from his wiki:
-He was a member of the Jekyll Island Club on Jekyll Island, Georgia.
-On Black Thursday in 1929, Lamont was acting head of J.P. Morgan & Co. Five days prior to the Crash, President Herbert Hoover had contacted Lamont with concerns about the rampant market manipulation by Wall Street insiders, and the systemic risk it presented to the stock market. Lamont reassured the President that there was no cause for concern, and no need for government intervention, saying "The future appears brilliant!"
The market crashed the following Thursday. In an attempt to stop the panic, Lamont organized Wall Street firms to inject confidence back into the stock market through massive purchases of blue chip stocks.
