Miroslav Hajn

Miroslav Hajn was a chief designer at ČKD-Praga, one of the largest engineering companies in the former Czechoslovakia and today's Czech Republic.^[1]

Hajn first was a founder and chief designer at Avia, along with Pavel Beneš, in 1919. The two began repairing planes in a workshop within the complex of an old sugar factory in Prague.^[2] One year later, they designed their first two-seater plane: the Avia BH-1. From 1923 to 1925, the two developed the Avia BH-7, BH-9, and BH-11 monoplanes, launching the era of biplane fighters. The BH-11 won the Coppa d' Italia prize. Three years later, their Avia BH-21 fighter was considered one of the world's best planes.^[3]

In 1930, Hajn and Beneš came to ČKD-Praga. The first aircraft they designed was the Praga E-39 in 1931.^[1]
