Rabbeinu Pinchas Horowitz was born in 1730 in Chortkiv (Ukraine). He served as a Rav in Witkowo, Poland, and then later in Lachovice (Liachavičy, Belarus). In 1771, he was appointed Rav of Frankfurt where he served alongside Rav Nosson Maz (author of Binyan Shlomo), who was the Rosh Yeshiva. Rav Horowitz authored numerous works, many of which became classics, including the sefer Haflah on Kesubos, Hamakneh on Kiddushin, and a lengthy commentary on Chumash called Panim Yafos. Rav Horowitz served as the Rav in Frankfurt for more than 30 years, until his passing in 1805. He was succeeded by his son Rav Tzvi Hirsch, author of the sefer Machaneh Levi.
