Jakob Herzstark was born in 1867, he studied mechanical
engineering, but had to stop because of the death of his
father. He worked as a salesman in the textile business.
His love of machines made him to work on the development
of office machines. After several years in this field, he
founded the calculator factory "Austria"
Herzstark & Co, Vienna. He improved the Thomas-system
and started the production of his own stepped-drum
calculator. There were several models. Model III had 6 digits in the setting register, 12 in the result register and 7 in the counting register. Model IV had 7 digits in the setting register, 12 in the result register and 7 in the counting register. It had a locking mechanism for the crank (against operating errors) and a mechanism to shift the carriage by pressing a key. Model V was made with 7 (9) digits in the setting register, 14 (18) in the result register and 7 (9) in the counting register. Model V could be provided with an electrical motor."
