Bart Janssen was born in the Netherlands. He is trained as a physicist, with a specialism in Elementary Particle Physics. Janssen worked for 5 years as a Research Scientist at CERN in Geneva. Subsequently working for 15 years for a financial company in Switzerland.
During his career Janssen attended short drawing and sculpture courses but was never able to fully develop his artistic ambitions to his satisfaction.
Since 2015 sculpture has played an important role in his activities. Without a formal art education Janssen has learnt the craft through a large number of workshops, mainly from (ex-)tutors at the Florence Academy of Art, Heatherley School of Art, and the Art Academy London. He has lived in London since 2016.
Janssen was elected member of the Society of Portrait Sculptors (SPS) in March 2021.
