"The Späth (often spelt Spaeth) family created one of the world's most notable plant nurseries of the 19th and early 20th centuries. The nursery had been founded in 1720 by Christoph Späth but removed to the erstwhile district of Baumschulenweg (lit. 'nursery way'; now part of the Treptow-Köpenick district) in south-east Berlin in 1863 when Franz Ludwig Späth (1839 - 1913) succeeded his father Ludwig as manager when aged only 25. By the end of the 19th century, the nursery was the largest in the world, occupying 120 hectares. In 1874 Franz built a mansion on the site, now part of Humboldt University and, five years later, established an arboretum." - (en.wikipedia.org 03.10.2023)
