The science cabinet at the Higher Real School in Karlovac contained 277 demonstration machines by the 1880/81 school year, a collection maintained and expanded by Martin Sekulić. A physicist and mathematician operating within the Austrian Empire, Sekulić represented a rare academic presence in the Croatian community of physicists during the late nineteenth century.
Academic and Research Career
Born in Lovinac in 1833, Martin Sekulić spent his career as a teacher at the Higher Real School in Rakovac, which is located in modern-day Karlovac. Beyond his classroom responsibilities, he maintained an active profile in regional intellectual circles, serving as a corresponding member of the Yugoslav Academy of Sciences and Arts and the Croatian pedagogic and literary society. He utilized German as a primary language for scholarly communication, contributing articles to the Annalen der Physik in 1872 and 1875.

Sekulić published specialized research in the Rad journal of the Yugoslav Academy of Sciences and Arts. His 1871 treatise, Fluorescencija i calcescencija, examined the luminescence of specific elements and contained a prediction regarding electromagnetic oscillations occurring at varying frequencies. In 1873, he published Iztraživanje sunčane duge, an investigation into the visible spectrum of solar light. As the custodian of the school's science cabinet, he developed specialized equipment, including a modified spectroscope utilized for student demonstrations.
Influence on Future Generations
Historical analysis of Nikola Tesla's education suggests that Sekulić played a formative role in the inventor's career. Between 1870 and 1873, Tesla attended the Kraljevska Velika Realka in Rakovac. In his 1919 autobiography, My Inventions, Tesla attributed his initial interest in electricity to demonstrations conducted by his physics professor. While Tesla did not explicitly name the individual, biographer Ćiril Petešić concluded the evidence points to Sekulić as the teacher responsible for these demonstrations.
Death and Legacy
Martin Sekulić held citizenship in Hungary and the Austrian Empire throughout his life. He concluded his career and life in Zagreb, where he died in 1905. Following his passing, he was interred at the Mirogoj Cemetery. His contributions remain documented through his published articles in German and Croatian, and his work in establishing experimental physics foundations within the Croatian educational system.
