He started the company in 1974 and grew it into the largest Canadian-owned drug company.Canadian Business magazine recently assessed his fortune at $4.77 billion, making him the 15th richest person in the country.Sherman faced legal action from family members alleging they had been cut out of the company over the years.As a producer of more than 300 generic pharmaceutical products, Apotex has itself seen a number court cases, as companies have pushed back on its efforts to sell cheaper no-name options.Honey Sherman, 70, was on number of boards, including the York University Foundation and the Simon Wiesenthal Center.The Shermans were among Canada’s most generous philanthropists and also organized funding of charitable causes through the Apotex Foundation. The couple made numerous multimillion-dollar donations to hospitals, schools and charities and had buildings named in their honour.
