Hans Nussdorf

Nussdorf is mainly known as the architect who finalized the works at the Martins tower of the Basler Minster.[5] The towers construction was initiated in the 12th century, but had to undergo renovation after the 1356 earthquake in Basel.[5] That the Martinstower was to rise more, was assumingly only decided in 1414.[6] It was the year that a mason from Strassburg arrived in Basel to assess the towers fundaments for an eventual further rise of the tower.[5] In 1470 another mason inspected the fundaments of the tower who also approved a further rise of the tower.[6]

In 1488, Nussdorf presented his plans for the completion of the Martins tower to the city council which approved them.[7] The construction of the tower begun in 1489, the year is marked in stone.[6] In 1496 and before the last stage of the completion of the tower, several other master masons were invited to give their approval on the towers fundaments. They approved and on the 23 July 1500, its construction was completed with the addition of the finial on the top.[4][8]

On the Martinstower there is a bust of about 40 cm,[5] which is strongly assumed to depict Nussdorf.[9] Beside's the bust, on the same working block of sandstone from Wiesental there is a masons sign to be seen.[9] He wears a leather cap under which some locks of hair are to be seen.[9][5] The bust is hewn out of high quality stone and is located at the north-face of the tower, which is less affected by the weather.[9] According to the appointments of the Minster masonry, he worked also on the ceiling of the small cloister and the surrounding walls of the large cloister.[5]

As the master mason of the Minster, he was one of the best earning craftsman in Basel.[10] Master masons were only hired or promoted for larger projects such as the Martins tower.[11] The master mason also had his personal workbench in the masonry of the Minster. After some remarkable accomplishments, he would be awarded some presents such as a considerable amount of wine or cereals.[10]

Nussdorf had also been contracted to work on a church in Delémont in 1481, but was accused of not fulfilling the contract in 1485.[12] He defended himself by arguing he had an overload of work as also in 1481, he had been hired to be the master mason of the Leonhards church.[12] He doesn't appear to have worked on both of the churches and in the case of the Leonhards church he was replaced by the Austrian Hans Niessenberger in 1491.[12] Niessendorf then accused Nussdorf of having insulted him which lead to a trial before court.[12] Niessenberger wasn't able to finish his work at the Leonhards church and seemed to have died by 1493.[13] In 1496 Nussdorf returned to the Leonhard church under a detailed contract in which he was assured not to be held responsible for the eventual mistakes of his predecessors.[14] But the scholarship doesn't view Nussdorf as the main architect of the Leonhards church, as a considerable amount of its construction was done after Nussdorfs death in 1503.[15]

Nussdorf was closely related with the masons guild of Strassburg, which in 1497 held their reunion in Basel explicitly "due to its famous master".[16]
