Gottlieb Müller was a Swiss lithographer, painter and etcher.

Gottlieb Müller was the son of the primary school teacher Gottlieb Müller. He completed an apprenticeship as a lithographer at the Winter company in Zurich. In 1902, he went on a journey that took him to Ulm for a year and to Paris for two years. Later, he stayed in Leipzig, Munich and Dresden. In Belgium, where he stayed in Brussels, Antwerp, Mechelen and Gent, Müller created the first etchings and graphics that made him a valued artist. Later, he lived in Paris for another three years.

When Müller returned to Switzerland in 1913, he worked at Orell Füssli in Zurich. He then settled in Brugg as a freelance artist. In 1922, he married Irma, née Hohl. In 1925, Müller succeeded Emil Anner at the Brugg district school, where he worked as an art teacher until his death.
