Sertarikzade Mehmed Emin Efendi was born in 1098/1687 and became one of the leading sheikhs of the Cerrahi branch of the Halveti order. As a guide who continued the path of Nureddin Cerrahi, he was so influential in the order's development that he came to be called its "second pir." He carried out spiritual guidance at the Sertarikzade Lodge named after him in Nişanca, Eyüp. He died in 1173/1761 and was buried in his tomb in the cemetery of that lodge. His tomb is among the visited sheikhs' graves of Eyüp today.
