Louis Couperin
He made many solo recordings of harpsichord works (including Louis Couperin, J. S. Bach, Thomas Arne, William Byrd's "My Lady Nevells Booke"), and did much to promote the clavichord in the "Secret Bach/Handel/Mozart" series of recordings, which puts in historical context the most common domestic instrument of that epoch. He owned a collection of historical keyboard instruments.
