Sedlacek was born in Breslau, Poland in 1891 and in 1897 his family moved to the Austrian city of Linz. He first studied architecture before going on to study chemistry in Vienna. Throughout his life, although his studies may have varied, he continued his passion and talent for painting and drawing before co-founding an artist association in Linz.

His studies came to an halt at the break of WWI when he was called to a duty of service. On his return in 1921 he worked at Vienna's Technical Museum.

Sedlacek turned his concentration to oil painting and in 1927 he joined a group of artists includes sculptors, painters and architects who broke away from the Association of Austrian Artists. This revolutionary group was known as the Vienna Secession. The group was first formed in 1897 with Gustav Klimt as the first president. The ideology of the group was to create completely original art forms which were not constrained by the past.

Although Sedlacek's work is hard to define, it can be categorised as part of the post-expressionist movement of New Objectivity, or Neue Sachlichkeit. Works like Sedlacek's from this category have a ethereal quality, and are somewhat nightmarish with strange figures and unsettling landscapes.

In 1939, Sedlacek was called up for military service in WWII, following a tour of duty in Norway and Russia, he was listed as missing in Poland in 1945.
