William York Macgregor, a painter, was the son of Glasgow shipbuilder.
Macgregor studied under James Docharty and later under Alphonse Legros at the Slade School of Art in London. His early landscapes were influenced by the broader style of James Paterson, who had studied in Paris. He is often regarded as the father of the Glasgow School. From 1888-90 he was in South Africa because of ill health. On his return his works became more abstract and sombre in colour.
In 1885 he was elected a member of the Royal Scottish Society of Painters in Water Colours and in 1892 he joined the New English Art Club. He was elected an associate of the Royal Scottish Academy in 1898, becoming a full member in 1921. He exhibited at the above institutions, as well as at the International Shows, and at Agnew and Sons Gallery, Dowdeswell Galleries, Connell and Sons Gallery, Glasgow Institute of the Fine Arts, Walker Art Gallery in Liverpool and Manchester City Art Gallery.
