Steel magnate Eric Samson, best known for building Macsteel into one of South Africa’s largest companies, has died aged 83.   The octogenarian billionaire – who shied away from the spotlight throughout his life – died in Newport, California. He had a career spanning more than five decades in the steel industry and made his fortune, which was valued at some $1.1-billion by the Bloomberg Billionaires Index in 2015 and over $1-billion by Wealth-X in 2018, primarily through steel and real estate assets.
