Sven Axel Theodore Tullberg (27 February 1852 – 15 December 1886) was a Swedish scientist who studied plants, ancient life, and the Earth's structure. He made important discoveries that helped people understand the natural world better. Tullberg was known for his work in botany, palaeontology, and geology.

Because of his contributions, a special group of plants was named after him. The subgenus Svenax comes from his first two names, Sven and Axel, showing how much his work meant to science.

Sven Axel Tullberg was born in Landskrona in Skåne County, Sweden. He studied geology at Lund University and became a professor there in 1880. He worked as a geologist and palaeontologist, studying plants and ancient life forms, especially in Skåne.

Tullberg wrote about many plants, such as the genus Ranunculus, and later studied ancient sea creatures called graptolites from long ago. His work helped scientists understand more about Earth's history.

Selected works

Sven Axel Tullberg wrote many important papers about plants and ancient life forms. Some of his works include "Some Didymograplus Species in Lower Graptolite Crime at Kivik's Esperöd" from 1880 and "Trenne New Graptolisms" also from 1880. He also wrote about graptolites described by older Swedish writers in 1882.
