The fluidity of inventor networks

The Individual Inventor

Inventor networks in emerging key technologies : Information technology vs . semiconductors

We analyze the development of the German knowledge base measured by co-classifications of patents by German inventors and relate this technological development to changes in the structure of the underlying inventor networks. Our central hypothesis states that technologies which become more central to the knowledge base are also characterized by a higher connectedness of the inventor network. We...

Pierre Fauchard the “inventor” of orthodontics

No one before Pierre Fauchard had claimed to be able to move teeth except Celsus who suggested applying finger pressure to a tooth that was erupting in the wrong direction. Fauchard advised dentists to examine a patient’s mouth and occlusion first and then, if necessary, to use one of a number of methods he proposed to ‘‘straighten’’ irregular teeth. The principal device was a ‘‘plate,’’ a smal...
