Omar S. Knedlik (December 21, 1915 – March 14, 1989) was an American inventor and businessman. He was best known as the inventor of the ICEE frozen drink. He was born and raised a poor farm boy in Barnes, Kansas in 1916. Knedlik was a World War II veteran who bought his first ice cream shop after the war. He owned several hotels before moving to Coffeyville, Kansas, where he became the owner of a Dairy Queen in the late-1950s. Knedlik did not have a soda fountain, so he served semi-frozen bottled soft drinks. He found that they were immensely popular, so he worked with a Dallas company to develop the ICEE machine. It took him five years to replicate the consistency in slushy soft drinks. In the mid-1960s, the first ICEE machines were sold in the United States.
