Ambrosius Lamm founded his porcelain decorating studio in Dresden in 1887. He began by painting Meissen blanks, but later decorated porcelain from other factories as well.
Ambrosius Lamm quickly gained recognition for his artistry. His specialties were mithological scenes, floral decorations in the Dresden style, and scenes inspired by Watteau paintings.
Ambrosius Lamm's (his last name means "lamb" in English) mark was a lamb. He covered manufacturer's marks with a golden rose mark.
In 1934, the studio was taken over by Ambrosius' daughter Clara Lamm and Rudolf Pitschke, who had previously worked for Ambrosius Lamm. When Dresden was bombed in 1945, the studio ceased to exist.
