Hermanus Ellen (Herman) Mees (18 September 1880 in Veendam – 28 November 1964 in Zuidlaren) was a Dutch artist, active as painter, watercolorist, draftsman, pastelist, lithographer, and academy lecturer.^[1] He was specialized in portrait painting.

Mees, son of the physician Willem Mees and Geertruida Hermina Oving, moved in 1897 with his family from Veendam to Rotterdam. There he passed his exams for the Hogere Burgerschool in 1899. He studied architecture at the Polytechnic School in Delft for one year in 1900, attended the Rijksakademie in Amsterdam from 1901 to 1903, and in 1902-1903 also the Academy of Visual Arts in Rotterdam, and the Academy of Fine Arts in The Hague from 1904 to 1905.^[1] In The Hague he graduated in 1905, obtaining a teacher diploma for secondary drawing education. He had studied under August Allebé and Willem van Konijnenburg.

Mees was interested in theosophy. The theosophical philosophy prescribed a simple life without much needs. After obtaining this degree, he went out into the world. After wandering in London, Paris, Munich and Dresden, he settled in London, where the headquarters of the Theosophical movement were located. There he met Arthur Ayliffe with whom he had many philosophical debates. He spent much time in the London parks, making hundreds of pencil sketches and pencil studies. In 1914 Mees moved to Spain, but soon had to flee because of the war.
