The ceramic artist Olga Sigmundová came from Slovácko in south-eastern Moravia. She attended the Secondary School of Applied Arts in Brno before briefly continuing with art education at the local Faculty of Education under the sculptor Vincenc Makovský. During her studies, she met her future husband, the painter and ceramicist Zdeněk Sigmund (1924–2017), who came from a long line of artists of the same name from Heřmanův Městec near Chrudim. The couple lived and worked in Heřmanův Městec.

Olga Sigmundová focused exclusively on ceramics, particularly traditional forms such as ceramic tiles and figurative sculptures with a thrown base. She often used glazed stoneware with embedded glass. In addition to functional ceramics and small sculptural works, she created a number of wall-mounted and three-dimensional objects for public spaces in East Bohemian towns—including Heřmanův Městec, Chrudim, Pardubice, and Havlíčkův Brod. These were artistic works which, from the second half of the 1960s, were required for all public buildings, such as administrative offices, service buildings, schools, and public spaces. Like many other artists whose work was state-controlled and regulated, Olga Sigmundová often turned to natural motifs, which allowed her to avoid politically charged content in her art.
