David and Simon Reuben

The Reuben Brothers rank in the top of the wealthiest people in the UK. Simon Reuben made his wealth by buying real estate and importing carpets, while David started making his fortune by trading metals. The two joined forces and bought assets through TransWorld Metals, a Russian metal trading company. At one point, they are said to have controlled up to five percent of the world’s aluminum output. Together, they are ranked 80th on Forbes list of billionaires.

They eventually sold their shares in TransWorld Metals and shifted focus to build a property portfolio in the United Kingdom. They are also well-known philanthropists, having started the Reuben Foundation, which funds educational and health care causes.
