Christophe Gamard, Gamar or Gamart, was a 17th-century French architect, who worked in Paris and died there in 1649.
[1] He was a master mason in 1613, an architect of the old Saint-Sulpice in 1623 (and began its reconstruction after 1643), and a city juror (juré de la Ville) in 1626.
He was an assistant of Claude Vellefaux, the supervising architect (architecte voyer) of the Abbey of Saint-Germain-des-Prés, and succeeded him in that position in 1627.
Widowed, he married Marie Gillier in 1648, despite the opposition of his sons.
[2] His brother, Philippot Gamard, worked on the Hotel de Nemours, rue Séguier [fr], in 1620, and at houses, current rues de Sévigné and Rue des Trois-Portes [fr] between 1616 and 1619.
