After his school education, law studies at the Universität Heidelberg and a trip to Italy and Switzerland, which was financed by paternal grants, Joseph Euler embarked on a career as a notary public.
In March 1842, the Ober procurator, an organ of the administration of justice in Prussia, instigated an investigation into an alleged misconduct on Euler's part.
This resulted in a specialist publication entitled Über das Notariat in Rheinpreußen mit Rückblicken auf die altpreußischen Provinzen und Frankreich (Leipzig 1844).
[2][3] A private performance of Bach's Toccata and Fugue in F major by Johannes Brahms took place in Euler's house in autumn 1853.
The Düsseldorf Anton Bloem - like him a member of the bourgeois-democratic movement of the Rhine Province - was also elected to the popular representation that was to give Prussia a new constitution.
[7] After the state of siege was lifted, new democratic associations were formed, in which supporters of the Verein für demokratische Monarchie and some reform conservatives significantly joined forces.
The Prussian state honoured Joseph Euler in 1874 by awarding him the title of Justizrat and the Order of the Red Eagle fourth class.
