Born in Siberia of politically active parents, refugee to Germany from Soviet oppression, Dan Broido took a degree in Mechanical Engineering in Berlin, and became an engineer at the firm Rotaprint, who sent him to the UK in 1934 to work in their London branch. He worked for Caterpillar Tractors during World War II on nationally important work, and subsequently for a Company interested in developing automatic reading equipment. Broido filed over 100 patents including one of the earliest bar code systems.
The company was taken over by ICT but in 1956 he was recruited by LEO Computers as Chief Mechanical Engineer charged with developing optical reading facilities. This resulted in the development of Lector and later Autolector.
When LEO, and later ICL started selling computers in Eastern Europe including Russia, Broido played a key role in the success of that enterprise.
A biographical sketch of his career can be found on pages 202 to 203 in the book LEO: the World’s First Business Computer.
