Marinus (nickname Bob) Zijlmans (Rotterdam, 1918 – ibid., 1992) grew up in a Catholic family. He attended the Antwerp Art Academy as a student of Constant Permeke, and also the Academy of Fine Arts in Rotterdam. After the war, Zijlmans traveled extensively and lived for several years in England and Indonesia. He subsequently developed into a painter and monumental artist. He created mosaics, stained-glass walls, (glass) paintings, and sculptures, among other works. The human figure was a constant factor in his work. Zijlmans worked primarily on commission in Rotterdam and was a member of the General Catholic Artists' Association (AKKV). In the mid-1950s and 1960s, Zijlmans received considerable press coverage for his paintings and drawings of human figures, reminiscent of the stillness in the work of Dolf Henkes. In the 1970s, he participated in a group exhibition at De Doelen. Read more here an article about this artist.
