Rasmus Malling-Hansen was an inventor, educator, scientist, pastor, and linguist. The history of his writing ball and other related inventions can be found on the web site of the Rasmus Malling-Hansen Society, at www.malling-hansen.org. The web site includes a thorough biography, many photographs, and numerous pages devoted to his many different accomplishments and interests.

The next time you are in Copenhagen, please visit the Royal School for the Deaf where Malling-Hansen was the principal. There is a commemorative monument in the school courtyard. If you can't make it to Denmark, feel free to visit the school in a virtual way through the Society's web site and/or the School's own website, which is www.skolenpaakastelsvej.kk.dk.

Keep your thinking cap on!
