Louis Weirter (Whirter) was born in Edinburgh and studied at the Royal Scottish Academy Schools, and in Paris. He is best known for his pictures of the Great War, but he also did a lot of architectural paintings and etchings. Somewhat confusingly, his paintings bear the signature "Louis Weirter," while his etchings are signed "Louis Whirter." He illustrated a number of travel books. He lived in London and at Étaples in France.

Louis Weirter, the Scottish artist and inventor, died on the night of January 12 at his home in Onslow-gardens, South Kensington, at the age of 61, it is learned from The Times of London. He was an original member of the Scottish Society of Artists and exhibited at the Royal Academy, the Paris Salon and other exhibitions in many parts of the world. Of his war pictures, The Battle of Courcelette was bought for the national collection at Ottawa. Peronne is also at Ottawa, and War in the Air is in the British War Museum."
