Carl Gotthelf Kind (born June 6, 1801 in Linda (Brand-Erbisdorf) ; † March 9, 1873 on his estate on the " Goldenen Bremm ", "La Brême d'Or", near Spicheren , France) was a German mining technician .

The son of an old mining family, father and even the grandfathers on both his father's and mother's side were active in the mining industry and worked in mining from an early age. Thanks to his technical talent, he was soon entrusted with other tasks, for example he was involved in drilling tests that Saxony had carried out in 1823 near Borna and in 1824/26 near Groitzsch for the purpose of developing salt deposits. The drilling was unsuccessful, and after the end of the company, Kind resigned from the civil service and hired the drilling specialist Carl Christian Friedrich Glenck . The drills of that time suffered from frequent breakage of the rigid rods, which significantly impaired the progress of drilling. Kind's invention of free fall and the improved sinking technique of the drilled shaft were of outstanding importance for efficient drilling .

In 1846 Kind succeeded in drilling a hole in Mondorf near Luxembourg to reach a depth of 730 m. Although this was not a world record, as is often claimed, since a depth of over 1000 m had already been reached in China, it was at least a record depth for Europe and America. The purpose of the Mondorf borehole was to search for an exploitable salt deposit. This could not be found, but a thermal water source that led to the construction of the Mondorf thermal baths, which began operating in 1847. Before that, Kind had already unsuccessfully drilled for salt in other places in Luxembourg, namely in Zessingen (1837–1839) and Echternach (1839–1840); Another borehole took place in the German border area near Besch (first borehole: April 4 - July 11, 1840; second borehole: July 24, 1840 - February 15, 1841).
