89a - Jean MEDERNACH (1834 - 1914) [1]

Johann MEDERNACH was born 1834 in Larochette in a family of Wollenweber, drapiers, known as MEDERNACH-REUTER. [2]

The Larochette Census of 1861 shows that Johann and his brother Adam had joined their father Mathias in the drapier business [3].

One year later, on 19 June 1867, MEDERNACH submitted a description and two drawings to illustrate his invention: 

The administrative file does not contain any additional information. No indication could be found that the patent was granted.
