Hannah Fenn is a violin maker in Philadelphia, Pennsylvania. She is a seventh generation maker from the Gläsel family from Markneukirchen. Hannah was first immersed into the violin world at a young age by her mother, who would import and wholesale strings and violin accessories from their home as JFennInc. She received a degree in Arts with emphasis in drawing and painting at Ohio University. 

Soon after she moved to New York and worked for Glasser Bows in the Bronx.  She then quickly decided to pursue violin making fully and did a six month repair study with her cousin Kurt Gläsel in Gelsenkirchen, Germany before enrolling in school.  In October 2015, she started at the Violin Making School of America and finished in February 2018.

  She apprenticed with Jordan Hess for two years and then worked together at Sugarhouse Violins in 2021 with an emphasis in making new instruments. Hannah then worked at Potter Violins in Washington D.C. in 2024 under Chris Jacoby. She currently can be found at Fred Oster’s Vintage Vintage Instruments working on restoration while continuing to make.
