Jan Brons was born in Wagenborgen (holland) in 1865.
His father was a carpenter and also Jan became one after his school.
Jan Brons had a natural talent with things mechanical and, within a couple of years, had begun production of paraffin engines.
The diesel engine and its emergence on the European market attracted Jan Brons' attention as the system of the future.
In those early days the diesel engine suffered fuel and air pump problems so Jan Brons set about developing and building an engine that, while operating on the diesel principle, eliminated the troublesome fuel and air pumps.
This was no simple task but, after two years of experiments, an engine using the Brons pre-chamber design had been produced.
In 1904 he got the German patent to protect his invention.
In 1907 the new factory was build in Appingedam.
In 1911 they decide to open there own foundry.
The Brons engines enjoyed a good reputation and, by 1920, some 95% of stationary engines production was being exported.
By 1927 the Brons company were even building diesel engines of conventional direct injection design, operating on both two and four stroke principle.
The last Brons pre-chamber engine was build in 1946. 
Even by the Brons company there where problems to sell their engines (example) during world war one and two.
