The roots of Sodexo’s business lie in a small shipping-supply company run by Pierre Bellon’s family, which since the beginning of the 20th century had operated a ship chandling business in Marseille. Pierre Bellon started Sodexo in 1966 because he saw a business opportunity in providing food and catering services to local companies and then to schools, hospitals, and other institutions. Just one year later CNES, the French space agency, which was a client, asked Sodexo to organize cleaning and maintenance for its base in Guyana as well. That was an early sign that if we did a good job for our clients, they might lead us to expand into services we hadn’t imagined providing.
