R. Menashah Eichenstein (1865-1935), a Zanzer hassid, was the son of R. Issachar Baer of Alsoverczke and the son-in-law of R. Joshua Horowitz of Dzikov. He published his first book, Alfei Manasseh on Shulhan Arukh Hoshen Mishpat (Przemysl, 1895). He later returned to Alsoverczke, and upon the death of R. Joshua Heschel of Rzeszov succeeded him as rabbi in 1904. He resided in Munkacs after World War I, and, in 1927, became rebbe in Alsoverczke. Among his other works are Torah ha-Asham (Podgorze, 1904) on ritual purity and uncleanliness and Alfei Manasseh (Munkacs, 1935) on the Torah.
