Grada Hermina Marius or G.H. Marius (June 7, 1854 – November 8, 1919) was a Dutch writer and painter. Marius was born in Hengelo but was trained under Jan Striening (1827-1903) in Deventer. She then moved to Amsterdam where she trained under August Allebé. In 1883 she settled in the Hague, where she became an art critic as well as continuing to draw and paint as a member of Pulchri Studio. She lived with her brother's family, and after he died in 1903 she stayed in the house with his surviving family and earned a living with her books, which were well received. Marius died in The Hague. Source: Wikipedia (en)
