The expansion of Zagreb throughout the 1920s remains the primary administrative legacy of Vjekoslav Heinzel, who served as mayor for much of that decade. Born in 1871, he transitioned from a career in architectural design to municipal governance, overseeing projects that reshaped the urban footprint of the city through significant infrastructure investment and neighborhood development.
Architectural Training and Early Career
Born as Alois Heinzel in Zagreb in 1871, he belonged to an entrepreneurial family. He pursued higher education in architecture at the Graz University of Technology and the University of Stuttgart, graduating in 1893. By 1896, he received his license for independent practice. During his early years, he executed various building projects across Zagreb. In 1906, he formally changed his name to Vjekoslav. His professional path shifted in 1910 when he began serving as a city councillor, followed by his appointment as head of the local Chamber of Trade and Crafts in 1912. He paused his architectural practice that same year to travel throughout Europe, eventually returning to organize food supplies in Zagreb during World War I.

Beyond his architectural work, Heinzel was an early proponent of motoring. In 1906, he helped establish the Croatian automobile club. His involvement in the field included active participation in competitive driving events. Notably, he secured a victory in the first championship race held for the Kingdom of Croatia-Slavonia in 1912.
Tenure as Mayor of Zagreb
Heinzel served as the mayor of Zagreb from 1920 to 1928, representing the Kingdom of Serbs, Croats and Slovenes. His first term ended in 1921 when the administration faced temporary dissolution, but he returned to office after an election in 1922 as a member of the Croatian Bloc. Despite political friction with the Party of Rights and the Croatian Peasant Party in 1926 and 1927, he retained his position through re-election. His administration focused on physical expansion, including the development of the Peščenica, Trnje, Trešnjevka, and Maksimir neighborhoods. Major public works projects during this time included the establishment of the Dolac Market, the construction of hospitals, and the reconstruction of Laščinska road, which was later renamed for him.
Modernization and Debt
The mayoralty of Heinzel was marked by rapid technological integration. On 15 June 1926, the city inaugurated its first 0.35 kW radio transmitter. Earlier that year, on 1 April, the city implemented its first automatic switchboard, capable of supporting 7,000 telephone subscribers. These extensive development efforts required substantial capital, leading the city to borrow 250 million Yugoslav dinars. This financial strategy became a frequent subject of public and political criticism.
