William McTaggart (25 October 1835 – 2 April 1910) was a Scottish landscape and marine painter who was influenced by Impressionism.
The son of a crofter, William McTaggart was born in the small village of Aros, near Campbeltown, Kintyre.
He moved to Edinburgh at the age of 16 and studied at the Trustees' Academy under Robert Scott Lauder. He won several prizes as a student and exhibited his work in the Royal Scottish Academy, becoming a full member of the Academy in 1870. His early works were mainly figure paintings, often of children, but he later turned to land and marine art, specifically seascape painting, inspired by his childhood love of the sea and the rugged, Atlantic-lashed west coast of his birth.
McTaggart was fascinated with nature and man’s relationship with it and he strove to capture aspects such as the transient effects of light on water. He adopted the Impressionist practice of painting out of doors and his use of colour and bold brushwork resemble qualities found in paintings by Constable and Turner, both artists whom he admired.
McTaggart was skilled in the use of both oil and watercolour and, in addition to Kintyre seascapes, he also painted landscapes and seascapes in Midlothian and East Lothian. Many of his later works depict the Moorfoot Hills which could be seen from his house near Lasswade, which he moved to in 1889.
He is regarded as one of the great interpreters of the Scottish landscape and is often labelled the "Scottish Impressionist".
He married Marjory Henderson (1856-1936), the daughter of another painter, Joseph Henderson (artist) RSW (1832–1908), Joseph's sons John Henderson (1860–1924) and Joseph Morris Henderson (1863–1936) also being painters. McTaggart painted a striking portrait of his father-in-law, Joseph Henderson, which hangs in the Glasgow Museum.
One of his pupils was the Scottish marine painter James Campbell Noble.
McTaggart is buried in Newington Cemetery, Edinburgh.
