[1] Matégot was born on 4 April 1910 at Tápió-Sully, a village about 20 kilometres (12 mi) from Budapest in Hungary.

[3] Matégot volunteered for the French army at the start of World War II (1939–45) and was taken prisoner, being freed in 1944.

[1] As a prisoner, he worked in a plant manufacturing mechanical accessories, where he learned the techniques and potential of sheet metal.

The Nagasaki chair is now held in the design collection at the Musée des Arts Décoratifs, Paris.

[1] Matégot continued to work on tapestry while engaged in other design activities, and a 1962 book La Demeure et les Éditions des deux mondes présentent les tapisseries de Mathieu Matégot documented some of his more important works to that date.
