Harris Ripps Memorial At ARVO

Harris Ripps

At this year’s ARVO meeting in Denver, please join us for a session honoring the memory of Dr. Harris Ripps.

Tuesday 1:00 pm – 2:30 pm

Room 708/710/712

Dr. Harris Ripps (1927 – 2014), Proctor Medal winner and past ARVO President, devoted his scientific career to studies on the retina and on causes of visual loss in inherited retinal diseases. He made significant contributions in many areas of vision research, including the kinetics of visual pigment bleaching and regeneration, electrical and chemical communication among retinal neurons and glia, and the cellular mechanisms of retinal degeneration. This memorial session will celebrate Dr. Ripps’ long time vision research career with talks by several his colleagues and students. The audience is welcome to contribute remarks during the open period of the session.

Who’s That? Wolfgang Baehr

This photograph of a young scientist in training is the second in the Who’s That? category here on Webvision.  The inaugural post in this category explains the idea behind these posts, but this post shows us, as you’ve deduced from the post title, a young Wolfgang Baehr seen in the Institute for Physical Chemistry at the University of Heidelberg in 1963.  Incidentally, one of Wolfgang’s sons is studying at Heidelberg University and looks shockingly like him in this photo.

Wolfgang was born in Mannheim, Germany and studied organic chemistry while at the University of Heidelberg before moving on to graduate school and then where we find him today in vision science.

Secret Societies And The Restoration Of Vision

The desire to restore vision, once lost is as old as man itself.

This article by Noah Shachtman in Wired’s Danger Room documents the discovery of a 250 year old code complete with secret society.  Its interesting reading from a variety of perspectives and has some wonderful photographs of the text and “blindfold goggles”, but what piqued my scientific interest was the ritual involving the restoration of sight and the potential evolution of the study of vision.

Sight and the mysteries of how we see is an equally compelling story that has inspired many throughout history to form in groups to discuss and study vision.  The Greek Empedocles in the fifth century BC had his “Emission theory” of vision which evolved through the Aristotle and Galen.  Plato also maintained that the eye possessed an “inner fire”.  But it was not until Alhazen and Leonardo DaVinci that experiments were carried out and documented that we started to establish our understanding of sight.  The Oculists mentioned in this article were thought to be early gatekeepers of the study of ophthalmology who would keep “charlatans” at bay that might cause people to lose their sight.  These Oculists came after William Briggs Theory of Vision and organized themselves into one of the many secret societies that exploded throughout the world in the 18th century, some of which served as safe houses for the discussion of science and religion which did not necessarily fit within popular belief or practice.  Of course modern understanding of vision was due largely to Hermann von Helmoltz in the 19th century which gave us early color theory and perception experiments, but it would be interesting work to follow the study of ophthalmology from the Oculists in the 18th century through Helmhotz work in the 19th century as it appears to be a partially secret history documenting the early study and restoration of vision loss.
