Bernard Jensen spent over sixty years as a pioneer in the holistic health field and operated his own health sanitariums in Altadena and Escondido, California, for over forty years. Jensen wrote and published over forty books including The Science and Practice of Iridology, Volume 1, which quickly became a classic in the field and established him as one of the world’s top authorities on the subject.

In 1953 he was awarded the International Iridology Gold Medal in San Remo, Italy, and in 1982 he received the National Health Federation’s Pioneer Doctor of the Year award.
