Trained in the ateliers of Emil Filla and Antonín Kýbal, Reindl left Czechoslovakia in 1968 and emigrated to Canada as a political refugee.

Following in the tradition of Czech Cubism, Reindl's style was greatly influenced by European modern art, in particular Pablo Picasso, Henri Matisse, Marc Chagall and Jean Dubuffet.

Reindl graduated in 1951 and married Helena Pokorná, a fellow art student and niece of the sculptor Karel Pokorný, in that same year.

Emil Filla's influence on Reindl’s work can be seen in his flattened perspective and bold use of color, typical hallmarks of Czech Cubism.

Reindl's work stands out for the bold lines of his drawings and the almost Baroque compositions, which are filled with apparently random details.
