American businessman and entrepreneur S. Daniel Abraham has an estimated net worth of $2.1 billion as of April 2016 according to Forbes. S. Daniel Abraham earned a great deal of prominence in the 1970's for introducing the diet product line, Slim-Fast. Aside from Slim Fast, he also works for S. Daniel Abraham Center for Middle East Peace as the Chairman.

In addition to being a billionaire businessman, S. Daniel Abraham is also active in engaging into several philanthropic activities. He is known to offer generous offerings to Jewish causes and to campaign for several democratic candidates including Barack Obama's presidential campaign. In fact, he is dedicated to various social causes which include encouraging peace in the Middle East, increasing educational opportunities as well as to improve overall nutrition and healthcare.

It was in 1977 when Abraham founded Slim Fast only after several failed attempts of introducing products like weight loss gum and itch cream into the market. In 1979, the company went public and by 1987, Slim Fast became a private company, again. In 2000, he sold the company to Unilever for only $2.3 billion.
