David Cunningham Garroway (July 13, 1913 – July 21, 1982) was an American television personality. He was the founding host and anchor of NBC's Today from 1952 to 1961. His easygoing and relaxing style belied a lifelong battle with depression. Garroway has been honored for his contributions to radio and television with a star for each on the Hollywood Walk of Fame and the St. Louis Walk of Fame, the city where he spent part of his teenaged years and early adulthood.
