Jozef Suchár was born in the village of Lemes, in what was then the Austrian Empire (now Lemešany, Slovakia) on 16 February 1857. Ethnically Slovakian, he spoke Slovak as his mother tongue, although he also spoke Hungarian fluently, as was typical for the region in which he lived. As a teenager, he moved to Eperjes, which is now known as the Slovakian city of Prešov. It was here where he began working in a salt mine, although he would later find work as a stonemason in different cities across Central Europe. Two of such cities he resided in were Budapest, Hungary and Bucharest, Romania. He would later return to Prešov, and from 1890 to 1920, he was employed as a railway switchman until his retirement. Additionally, he was active in the labor movement, and was involved with the Social Democratic Party in Prešov.
