His other interests in life were occultism, women, alcohol and gaming. He died in 1805 at age 33. With UV light becoming stronger each year due to the ozone layer getting thinner, it is surprising the filter manufacturers have not yet started using this as an argument for selling more filters. I have filters on all my lenses, not to protect the front element, no, I have them because of those UV rays.
