Robert was born in Dalgarven near Kilwinning in Ayrshire. He was apprenticed to a painter and decorator in Irvine around 1854, who also taught him how to paint landscapes.

He died in Edinburgh on 2 August 1923 and is buried in Dean Cemetery. His grave faces northwards to an east–west path in the inner north-west section, but is concealed behind larger graves.
