Hasan Chelipa, known as Esmailzadeh (born in Zanjan 1922 - died on 9 February 2007} in Tehran, was alive and well, an Iranian coffee house painter (and one of the last survivors of the generation of coffee house painters). His son, Professor Kazem Chalipa, is also a contemporary artist. Master Hasan Chalipa, who borrowed his artistic surname (Ismailzadeh) from his father's name (Ismail), was born in 1922 in Zanjan. But before he was born, his father passed away. With the help of his God-given talent, he got his first role-playing experiences from his childhood due to his enthusiasm and interest in the art of painting. As a child, he migrated to Tehran with his family, and at the age of 8, his mother, who noticed his son's great interest in painting, chose the late professor Mohammad Modbar to teach him. The immeasurable enthusiasm of the student and mastery of the teacher made Ismailzadeh a creative artist and painter. For 14 years, he learned the secrets of pen drawing and painting from the master. As his paintings showed the line, style and color of his master's pen. This collaboration, on the one hand, led to the tendency of talented and young painters to follow the style of his master, Mohammad Madbar, and on the other hand, led to the rise of imaginary religious and Shahnameh paintings among the public. It is said that both during the lifetime of Master Mohammad Modbar and after his death, he revealed such similarities with Master Modbar in terms of color and design that many people were surprised and doubtful when judging the paintings of the two. The Museum and Foundation of Master Hasan Esmailzadeh (Chalipa) is located in Tehran, Enghelab St., Vasal Crossroads, next to Soroush Publishing House.
