Ray Kroc was born on October 2, 1902, in Chicago, Illinois, the United States. His father, Alois "Louis" Kroc, originally from the village of Bøasy near Plzeò in Bohemia, was a man of great discipline. Employed with the telegraph company, Western Union, he rose to reach a high position in the organization. He was also a baseball fan, a craze Ray inherited from him.
His mother, Rose Mary nee Hrach, was born in Illinois. She was an affectionate lady and a homemaker. She also played the piano, earning extra money by giving lessons to children and adults. Ray also learned the piano from her, showing a natural affinity to it. As a child, his mother called Ray "Danny Dreamer" because he would daydream all the time.
He had two younger siblings; Robert and Lorraine. As children, Ray and Bob had very different inclinations and the two often found it difficult even to talk to each other. However, they came closer as they became older.
