Chancellor Simon Péchi (c. 1570/1575–1642) was a Hungarian Székely official, and wealthy supporter of Matthias Vehe and nobleman András Eőssi's Szekler Sabbatarians movement in Transylvania.
[1][2] The influence of Péchi's Sabbatarian prayer book contributed to the conversion of around twenty thousand Székelys to Sabbatarianism in the late sixteenth century.
[3] Samuel Kohn, Chief Rabbi of Budapest, and the first scholar to take an interest in the Sabbatarians among the Transylvanian unitarians, published a biography of Péchi as part of his studies in 1899.
