William de Blaise was born in Latvia in 1907 but settled in England in the 1950s. He became a prolific builder of harpsichords, turning out as many as 60 per year. This was largely thanks to his association with the Welmar piano company who made the harpsichord bodies for him (which was also why they were such solid and robust instruments) leaving de Blaise to concentrate on stringing, action, and tuning. Most of his more popular instruments were the 2-manual ones. but de Blaise also produced a triangular shaped, single manual spinet model which was quite popular for domestic use. However, due to the shortening of the scale, the tone was less satisfying.
