Gerard Gustaaf Muller (20 January 1861 – 26 March 1929) was a Dutch Impressionist painter associated with the Tachtigers literary movement.

[1] While there, Hendrik introduced him and his friends, Jacobus van Looy and Jan Veth, to a group called "Flanor", precursor of the Tachtiger (Eighties) movement.

[2] From 1884 to 1888, he studied at the Royal Academy of Fine Arts in Antwerp with Charles Verlat.

The following year, he returned to Amsterdam and took up residence at a house near the Oosterpark which would also be home to George Breitner and Isaac Israëls, among others.

[2] His work gradually came to show an obvious southern influence and many had Orientalist features.
