Leendert Johan (Leen) Muller was born in Leiden on 25 September 1879 as son of a tobacconist and his wife. In 1881 the family moved back to Amsterdam where his father had come from 6 years earlier. In 1893 Leen started at the "Teekenschool voor Kunstambachten" , an art school for budding artists and artisans. He passed the first year but after that there is no proof he continued his education. Recently a Brantjes piece came on the market signed with the LJM monogram. It appears he worked there for at least some time and followed Egbert Estie to PZH. He started at PZH on 1 February 1898 and in March of that year, he moved to Gouda. In 1903 he married Nelly Blok from Gouda with whom he got a son and a daughter, His long PZH career lasted till 1936, when he left with a stipend under the condition he would not work for other ceramics factories. He and his wife moved to Hollandse Rading and there he supplemented his income by selling his paintings and drawings. He died in 1969 in Oldenzaal, age 89.
