Carl Heinrick Ferdinand Werner was born in Heide, Denmark, on 21 August 1861, the son of Fritz Werner. He came to Australia in 1870 to live with an uncle in Ballarat, Victoria. Carl Werner and Henry Carter started business as jewellers, opticians and importers of optical instruments in Ballarat. In 1888 Carl married Margaret Lonie who was born in Victoria in 1865. They had four children: Fred, born 1889; Roy, 1891; Max, 1893 and Trina, 1900.
Carter and Werner opened branches in Launceston and Hobart and won two gold medals and one silver medal at the Tasmanian Exhibition in 1891-92.
Carl Werner went to London in 1896 to further his studies in optometry. He was one of Australia's earliest optometrists. He died in Melbourne at the age of sixty in 1922. His three sons were also prominent optometrists in Melbourne.
