Born in London, Ihlee began his artistic training at the Slade School of Fine Arts in 1906. He quickly gained notice at the Slade and was awarded numerous prizes in recognition of his skill. In 1914 the artist participated in two solo exhibitions at the Carfax gallery, London. He became a member of the New English Art Club and enjoyed many exhibitions at the Leicester Galleries. Ihlee later relocated to the South of France, where he became inspired by the lush landscape. The artist continued to exhibit in England regularly throughout his career. A significant retrospective of his work was held at the Belgrave Gallery. His work remains in the collections of the Victoria & Albert Museum in London, and in the Manchester City Art Gallery.
