Jaromir was born in Hnidousy, a town near Kladno in Czechoslovakia, on February 15, 1972. Since childhood, he always had a secret dream of being the best hockey player in the world. When Jaromir was 6 years old and was playing in a tournament against older kids, the coach of the other team asked his father why he wasn’t enrolled in a hockey school (only for 3rd graders and up) and his father said "he’s only in the grade 1". The coach walked away and shook his head and said "unbelievable". Jagr’s team won the game and he scored 2 goals.
