For more than 200 years after her death, Leyster’s work was either attributed to her husband Molenaer or Frans Hals. This seems partly due to their similarity in style, but there also seems to have been deliberate forgery: in 1893, Leyster’s signature was discovered underneath a forged signature of Hals on the 1630 painting called The Carousing Couple or The Jolly Companions.
Because Leyster’s legacy was overlooked for centuries of art-making and history, it is difficult to say precisely who has been influenced by Leyster’s work. It would seem that many of the artists who studied or cited Frans Hals or Molenaer as an influence may well be citing Leyster without realizing it. The realist paintings of Netherlandish painters such as Jacoobus van Looy and Isaac Iraels owe much to the style of Dutch Golden Age painting, where she was a leader among her contemporaries. Similarly, many key figures in both Impressionism and Realism studied the works of Dutch Golden Age painting as a means of considering the interaction between interior spaces and human life. Her impact is most likely larger than modern art historians can document.
