was a well-known watercolour painter and illustrator of the Victorian era. Helen Mary Elizabeth Paterson was born in Swadlincote in Derbyshire, England. Her sister and her father, a doctor, died of diphtheria in 1862, and the rest of the family went to live in Birmingham. In 1867 she went to study art at the "Female School of Art", a section of what became the Royal College of Art in London, and became an illustrator of children's books. She was a great friend of Kate Greenaway. On 22 August 1874, she married William Allingham, who was almost twice her age. At the time, she was employed in illustrating some of the novels of Thomas Hardy, and they were attracted to one another when they met. Helen Allingham illustrated several books, including Six to sixteen: a story for girls (1876), Happy England (1903) and The homes of Tennyson (1905), written with her brother Arthur Paterson. After her marriage to Allingham, she became a watercolour painter, and she was the first woman to become a full member of the Royal Watercolour Society.
