June Miles was born in London in 1924 and spent the first six years of life near Hong Kong. She studied at the Slade School, and during WWII she drew maps for the Admiralty Drawing Office. June was the first wife of painter Paul Feiler and the couple moved to Bristol where their three children were born. She later moved to Cornwall upon separating from her husband, though she continued to teach at Bristol Polytechnic and the Folk House in Bristol.
In 1978 she married the sculptor Paul Mount and they lived and worked in St Just-in-Penwith. It was during this time that June became fascinated with still life; one of the two major dedicated themes of her working life along with landscape painting. June is a member of the Penwith Society and exhibits throughout the South West.
