Born in Vienna in 1864, Bernard Hollander was a London-based psychiatrist in the early twentieth century. He is best known for being one of the main proponents of the interest in phrenology at that time. This title, originally published in 1916, looks at ‘the numerous nervous illnesses of men, in which the mental factor plays a large part, and which are known as functional disorders, to distinguish them from organic diseases’. He looks at the role of psychotherapy as an emerging treatment for these disorders. There is also a companion volume which looks at the Nervous Disorders of Women.
