J.H. de Bois was born in Amsterdam in 1878. He began his art dealing career in 1902 with the Van Wisselingh firm. In 1902 he joined the gallery of C.M. van Gogh, the uncle of the artist, and four years later became director of The Hague branch of that gallery. When The Hague branch closed in 1911, de Bois joined with the dealer Artz to form Artz & de Bois. Two years later he opened his own gallery in Haarlem. The business was liquidated after his death in 1946.
