Agreed it would be a fine memorial to a remarkable man. Thomas Guy, like many many people at the time, invested in the South Sea Company which was primarily a government debt holding company. The company was also awarded the monopoly on selling slaves amd goods to the Spanish colonies, but due to the Spanish war of succession the company never really got this trade underway or made much money from it. Guy's money was mainly made in trading government debt and being lucky enough tl get out before the South Sea Bubble burst. His main crime in my view was he did not care or perhaps realise how the company he invested in intended to make a profit on his investment. Something many of us continue to be guilty of today. I don't think it totally negates the good he did by using the money he made to found Guy's Hospital.
