Leon Jadin was born on 15 June 1878 in Nivelles (Belgium). He studied at the Lemmens Institute in Mechelen and at the Brussels conservatory under Alphonse Mailly (orgue). After his studies Leon Jadin became organist at the Saint Waltrude Collegiate Church in Mons.
I found no further information about the activities of Leon Jadin in the following years.
Leon Jadin died in 1967.
There is little known about the work catalogue of Leon Jadin. Published pieces are several works for organ, a Romance for violin and piano, pieces for piano and the song "Le Soir".
In my possession are the autograph parts of the "Sonatine pour 4 violoncelles" by Leon Jadin. The part for the first cello has also an autograph inscription by the composer to the cellist Georges Turc and is dated 16 December 1950.
