The surname Klamut is of Polish origin, with its roots traced back to the 16th century. The name is derived from the Polish word "klam," meaning "lie" or "deception." It is believed that the name was initially given as a nickname to individuals known for their tendency to exaggerate or tell tall tales.
The earliest recorded instances of the Klamut surname can be found in historical documents from the region of Lesser Poland, particularly in the areas around the city of Krakow. One of the earliest mentions of the name appears in the Krakow municipal records from the year 1592, where a certain Jan Klamut is listed as a resident of the city.
In the 17th century, the Klamut name gained prominence in the nearby town of Tarnow, where a family of that name owned a significant amount of land and held a respected position within the local community. Notably, Maciej Klamut (1621-1688) was a prominent landowner and benefactor who funded the construction of a chapel in Tarnow's parish church.
During the 18th century, the Klamut surname spread further across Poland, with notable bearers including Józef Klamut (1738-1802), a renowned theologian and professor at the University of Krakow. Another individual of note was Franciszek Klamut (1772-1846), a military officer who fought in the Napoleonic Wars and later served as a commander in the Polish uprising against Russian rule.
As the Klamut family dispersed throughout Poland in the 19th century, different regional variations of the surname emerged, such as Klamuth, Klamot, and Klamuth-Kozlowski. One prominent figure from this era was Jan Klamut (1823-1892), a prominent lawyer and politician who served as a member of the Galician Sejm (regional parliament) in the latter half of the 19th century.
In more recent history, the Klamut surname has been carried by notable individuals such as Stanislaw Klamut (1903-1982), a celebrated Polish writer and poet, and Jerzy Klamut (1925-2003), a renowned architect and urban planner who played a significant role in the reconstruction of Warsaw after World War II.
