Carl Rennoldson was born in Loughborough UK. His early training was in traditional cabinetmaking, working at the bench under the supervision of an established craftsman. Later he attended Shoreditch Teacher Training College at Egham, Surrey, obtaining a Cert.Ed., with distinction, in Craft, Design and Technology. It was during this period that he became interested in early keyboard instruments and built his first harpsichord, a large double manual instrument in the style of Kirckman.

Since 1983 he has been running his own furniture making and antiques restoration business and for 20 years also taught antique furniture restoration and conservation for the Kent Adult Education Service.

His interest in music comes from an early introduction to the violin, which he still plays. In 1993 he decided to further pursue his interest in early keyboard instruments at London Guildhall University graduating with a BSc (Hons) First Class in Musical Instrument Technology.
