The introduction of Bach to music had quite an impact. Before Bach, many were ill - tempered and most became well - tempered after Bach. Harmonically speaking, Back's composition were way ahead of time. He introduced unexpected chord changes. He also initiated the keyboard technique that is still used up to date.

Louis Comfort Tiffany was an American artist, painter, decorator and designer. He is particularly remembered for his influence on Art Nouveau and his contributions to glassmaking. Tiffany was responsible for the development of "Favrile glass," which was inspired by the work of Émile Gallé at the Paris Exhibition of 1889. This glass displayed several innovative characteristics, such as impressionistic effects, iridiscence and free shapes. This embodied many of the artistic elements that would later become popular in Art Nouveau.
