Doctor of Humane Letters
The degree of Doctor of Humane Letters (Latin: Litterarum humanarum doctor; D.H.L.; or L.H.D.) is almost always conferred as an honorary degree, usually to those students who have distinguished themselves in areas other than science, government, literature or religion, which are awarded degrees of Doctor of Science, Doctor of Law, Doctor of Letters, or Doctor of Divinity, respectively.
Doctor of Humane Letters degrees should not be confused with earned academic degrees awarded on the basis of research, such as Doctor of Philosophy, Doctor of Science or Doctor of Theology, nor earned professional doctorates such as Doctor of Medicine, Doctor of Osteopathic Medicine, Doctor of Podiatric Medicine, Juris Doctor, Doctor of Optometry etc.
