Turner began his career at McDonald's in 1956 as a grill operator and was quickly promoted. He was named Operations Vice President in 1958, when the firm had only 34 restaurants. In that role, he established strict guidelines for how McDonald's hamburgers and other products had to be served - including that fries "had to be precisely 0.28 inches thick", and that "exactly ten patties had to be formed from each pound of beef". "Quality, Service and Cleanliness" became his motto. He became Executive Vice President in 1967, then President and Chief Administrative Officer in 1968. He became CEO in 1973 and replaced
Kroc as Chairman in 1977, later named Senior Chairman upon Kroc's death. Under Turner, McDonald's expanded its operations to 118 countries, with over 31,000 outlets, and more than a billion hamburgers were sold. He retired in 1987, after which time he served as Honorary Chairman. ==Awards and memberships==
