Andrew Black (1850 -1916) was born in Glasgow and began his working life as a pattern-designer to a firm of calico printers in Glasgow. Like many other Scottish artists from the west coast, Black prepared for a painter’s career by taking Robert Greenlees’ classes at the Glasgow School of Art (1870). He received considerable encouragement as an amateur painter of landscapes in watercolour.

He then travelled to Paris to study under masters, Bouguereau and Fleury, an experience which strongly affected his work. Very soon, Black started painting his trademark seascapes in oils and turned to art full-time in 1877.

He specialised in marine pictures and is known for painting seascapes of harbours and fishermen along the shores of Ayrshire and Kintyre. He was a keen yachtsman and had an intimate knowledge of the waters around Scotland.

Black exhibited in the Royal Academy in Scotland and became a member of the Royal Scottish Society of Painters in Water Colours. He also exhibited for many years at the Glasgow Institute of Fine Arts.
