Flemish carillonneur, harpsichordist and composer. Known by 1729 as a carillonneur and clockmaker in his home town, Le Blan appeared from 1743 in Veurne exercising these occupations. In 1746 he succeeded Pierre Schepers as town carillonneur at Ghent, becoming town clockmaker in 1751. He acted several times as a consultant in carillon building (Ghent, Bruges, Dunkirk). In 1763 he gave a recital on a carillon with small glass bells which he had constructed. His only work known today is a Livre de clavecin (Ghent, 1752) containing six elegant suites.
