4. Papin was elected a Fellow of the Royal Society. He had earlier worked as an assistant to Christian Huygens (to whom he later returned) and was perhaps the prototype technician in the sense of having great manual dexterity and the ability to design and build a range of scientific apparatus. He was a major contributor to the air pump that is associated with Boyle. As Shapin states there was a degree of collegiality between Boyle and Papin and some joint publication. Perhaps more typical of the ‘invisible’ technician were John Flamsteed's paid assistants at Greenwich most of whom as noted by Shapin came from trades backgrounds and remained largely anonymous in scientific circles.
