William Applegate Gullick (1858 – April, 1922) was a publisher and inspector of stamps in New South Wales, Australia.

His father, a printer, lost all his money after he had married Sarah Dust, and was declared bankrupt in 1869.

[2] He was honoured to have his designs approved by the King, and Gullick expected these "emblems of distinction to be prized and guarded jealously".

The Lumière brothers' autochrome process that he used relied on using potato starch dyed to the three key colours of red, blue and green.

[3] His obituary does list his hobbies which included both coin and stamp collecting and he left a lathe, many woodworking tools and a camera.
