Onsi Sawiris is the third-richest person in Egypt, and the #401 in the world. He is worth $2.9 billion and made his millions as the founder of the business dynasty that includes Orascom telecom, hotels and construction. He was encouraged to study agriculture when he was younger, but found it boring and opened up his own contracting firm, which had to be rebuilt after it was nationalised in the 1960s.
