Scientists & Engineers on Postage Stamps

Over the past many decades, my involvement in stamp collecting (philately) has waned and ebbed with the amount of time available to dedicate to it. Commemorative stamps - from all countries - have always been of the greatest interest to me. Although I do not own most of the stamps pictured here, there are some that are in my collection. This is a small cross-section of what is available, and someday when there is more opportunity, I will scour the Internet for more examples.
