Sydney Leon Miller (24 December 1901 – 31 December 1983) was a prolific Australian artist celebrated for his black-and-white work as a cartoonist, illustrator, caricaturist and comic-book author. Known professionally as Syd Miller, he was employed as a staff-artist for Smith's Weekly from late-1922 until 1935, when he left to pursue a diversity of freelance work. Miller created a number of comic-strips during his career, most notably the iconic 'Chesty Bond' character as a marketing campaign for the Australian clothing company Bonds. He also wrote and illustrated the Rod Craig comic-strip which was serialised from 1946 to 1955 and syndicated across Australia and internationally.
