R. Winkler (1844-1932) was born in Lepontovic in the vicinity of Nitra. He served as the rabbi of Mad in Transylvania, where he headed a bet midrash. Among his students was R. Mordecai ben Joshua Briszk (1884–1944), founder and head of the yeshivah at Tasnad. R. Joseph Zevi Duschinsky (1868–1948) was his son-in-law. The three years R. Duschinsky spent in R. Winkler’s house were considered by him, due to his father-in-law's fine personality, as being among the main formative influences in his life. R. Winkler also wrote responsa on other parts of the Shulhan Arukh.
