Irmgard Sörensen-Popitz (3 June 1896 – 2 November 1993) frequently known as Söre Popitz was a German graphic designer who studied at the Bauhaus.

In her teenage years, Sörensen continued to pursue visual arts, going on to attend the craft college in Kiel.

In 1917 she matriculated at the Hochschule für Grafik und Buchkunst Leipzig, where she studied graphic arts, drafting, and advertising.

In her first semester, Söre Popitz attended a first year course covering design foundations taught by Moholy-Nagy, Wassily Kandinsky, and Josef Albers.

[1][2] From her departure from the Bauhaus until after the war, Söre Popitz was frequently employed by Otto Beyer, a publishing house in Leipzig.

Many of her earlier graphic design works feature heavy emphasis on geometry, while also straying away from bright and pigmented colors.
