Alexander Nikolai von Glehn (16 July 1841 in Jälgimäe Manor, Kreis Harrien, Governorate of Estonia, Russian Empire – 7 September 1923 in Brazil), was a Baltic German landowner and public figure, most notable for being the founder of the town of Nõmme (now part of Tallinn).
Glehn established a new settlement called Nõmme in the northern part of the lands of his Jälgimäe Manor.
The castle is surrounded by a park with several buildings like palm house (1900–1910), observatory tower (1910) and sculptures "Kalevipoeg" (1908), "Crocodile" (1908), all of those created by Glehn himself.
[2] After a departure for Germany in 1918, he went to Brazil to treat his ill son, Manfred von Glehn (1867–1924), in the warm climate.
On 12 November 2011 a sculpture by Seaküla Simson was unveiled beside the footbridge in the centre of Nõmme to honor Glehn.
