Grand Old Man
Prof. Fritz Hollwich (*1909, †1991) was a German ophthalmologist,
professor of ophthalmology and a director of ophthalmological clinic.
He worked in Munich, Jena and Münster. In his inaugural dissertation form 1948
he distinguishes a visual and energetic path of the sight apparats.
Three quarters of total light are considered to have the energetic function
and only one quarter to have a visual function. The energetic function is
demonstrated by observing the levels of hormones and other substances in the body.
Blind patients who regained sight after cataract operation helped him to
demonstrate how vitality is enhanced and substances are returning to their natural
levels when light can strike retina again. Prof. Hollwich observed stress hormone
levels decrease in his patients after he had daylight fluorescent tubes installed
in his waiting room. In this way he contributed to a better light in hospitals.
He is an author of many medical methods, more than two hundreds specialized
publications and of many books. There are ten or more editions of his Textbook
of Ophthalmology, which is even after sixty years still considered to be one
of the cornerstones of modern ophthalmology. Prof. Hollwich cofounded International
Ophthalmological Academy. In his works, he also refers to John Ott, a pioneer of
better artificial light. From the work of prof. Hollwich one can feel
truthfulness, scientifical verity, German precision and courage to present
things the way they are.
Dr. John Ott (*1909, †2000) was an American camera man and self-learned
scientist. While working on the time lapse pictures for Walt Disney's Secrets of life
series he found that some of the plants do not blossom and finally fade under
warm fluorescent light. Step by step he discovered that artificial light that
lacks some colour can have adverse effect on plants and animals. Large
importance is given to the blue light, which is weak in warm white light.
Ultraviolet light, which normally does not pass window or spectacles glass
is also considered important. Dr. Ott demonstrated that a light more similar
to daylight can soothe school kids, but also prison inmates.
In this way he demonstrated how different kinds of light affect our hormonal
system that, in the end, controls our body and our feelings.
Dr. Ott was the first to talk about mallillumination. He is a founder of
Time Lapse Research foundation, Bio Ecological Research Institute and Ott Lite
company, which is one of the first producers of fluorescent tubes with
rare-earth elements that enrich the spectrum of the light produced, enhancing
the colour experience. Dr. Ott published several books, several tens of articles,
made several thousands of lectures. In 1957, he was awarded a title of honorary
doctor of natural sciences by Loyola University of Chicago. John Ott is
an example of great enthusiast, unlimited by school indoctrinations,
a pioneer of better illumination who gained respect of both laic and scientific
public.
Dr. Norman E. Rosenthal (*1950) is a Southafrican psychiatrist
living in USA. In 1984 he published an article on seasonal affective disorder
(SAD) and it's healing by phototherapy. Dr. Rosenthal is an author or coauthor
of more than two hundred specialized articles. He published four books:
Winter Blues, The Emotional Revolution, St. John's Wort and How to Beat Jet Lag.
Dr. Jacob Liberman (*1947) is an American ophthalmologist
and author of Light - medicine of the future and Take Off Your Glasses and See.
He is an inventor of the EYEPORT eye training device and system.
