In the early 19th century Adriaan Mollen was professional falconer to Prince Alexander of the Netherlands. He was a brilliantly sympathetic falconer and was also equally famous for his technical skills as a maker of falconry equipment. His son Karl Mollen born in 1854 continued producing traditionally hand crafted falconry equipment and supplied the English and French aristocratic dynasties of the 19th and early 20th century. His artistic falcon hoods remained highly desirable in professional circles until his death in 1936 at the age of 82.
