The story
The driving force behind the establishment of the museum was Itche Mambush, together with Moshe Znaimer, who raised the funds for its construction. Among the founders of the museum were also Haim Bar-Lev, Haim Zadok, Aharon Rubinstein, Oded Messer, and Yosef Peker. Mambush persuaded Marcel Janco to donate a plot of land and fifty of his works for the project.
The museum building was designed by architect Moshe Zarhi on a voluntary basis. Zarhi described the design as follows: "The museum was designed as an inward-facing structure that includes a courtyard and entrance hall, a permanent exhibition hall, a temporary exhibition hall, open areas for performances, and auxiliary facilities. The halls and exhibition spaces, with their varying dimensions, are interconnected and create a continuous spatial sequence. Here will be displayed the works of Marcel Janco, each with its appropriate setting."
The cornerstone for the museum was laid in July 1981. The museum was built by contractor Zechariah Drucker and inaugurated on 21 June 1983 in the presence of the President of Israel.
