Grand Piano by Nannette Streicher and Son, Vienna, 1829

由兰丽缇施特莱歇尔父子制造的三角钢琴，维也纳，1829
当法官斯坦因于1792年去世，他的工作间是由他的女儿，兰丽缇（1769年至1833年），和她的弟弟安德烈亚斯·马特乌斯（1776年至1842年），被称为安德烈接管且不停地操作。1794年这两位姐弟把公司从奥格斯堡省搬到维也纳，在那里他们一起工作直到1802年，当安德烈成立了自己的工作间。兰丽缇，在此期间与一位钢琴家和作曲家，JA施特莱歇尔结了婚，作为一个女人能亲力亲为从事的专业生意，这确实是一种极为罕见的历史实例。此外，它几乎是一定的，她的角色不仅局限于前面的办公室。她还积极从事传承她的名字的乐器的设计和音乐整理。

When J. A. Stein died in 1792, his workshop was kept in operation by his daughter, Nannette (1769-1833), and her brother, Matthäus Andreas (1776-1842), known as André. In 1794 the siblings moved the business from provincial Augsburg to Vienna, where they worked together until 1802, when André set up his own workshop. Nannette, who in the meantime had married the pianist and composer, J. A. Streicher, is an extremely rare historical instance of a woman visibly in charge of a major business. Moreover, it is virtually certain that her role was not confined to the front office. She was actively engaged in the design and musical finishing of the instruments bearing her name.
