Alfred Ost (14 February 1884, Zwijndrecht – 9 October 1945, Antwerp) was a Belgian designer, watercolorist, illustrator, painter, draftsman and political cartoonist.

[1] After his first drawings, of a descriptive realism of animals and genre scenes, he addressed religious themes transposed into a contemporary popular context.

His war experiences, intensified by his bipolar disorder, caused a dark colorite and pessimistic themes to be introduced into his art works.

[2] He was born in Zwijndrecht near Antwerp, the son of Isidoor Ost (Mechelen, 1847), a coal merchant and Barbara Hamendt (Rupelmonde, 1846) .

As there were many positive reactions and a lot of fascination with the style, power, and dynamism of his art, he was offered to make drawings on all the walls all over the college.
