Mirza Husayn Isfahani (d. 25 Dhu'l Hijja AH 1330/6 December 1912 AD) was titled Mushkin Qalam by Nasr al-Din Shah. He was a follower of the Baha'i faith and spent most of his adult life in the Ottoman territories following the Baha'is and their spiritual leater Baha'ullah, for whom he eventually became scribe. He was active in spreading the word of Baha'ullah and spent some time in India. His signature is often: 'The servant of the gate of Baha' Mushkin Qalam'.
Mushkin Qalam wrote in many styles but is known for his large decorative calligraphic panels, particularly those in the shape of birds. Apart from numerous calligraphic panels, he copied Baha'ullah's writings, which he completed in 1892.
