“If A Piece Of Lead Broke Off…It Could Float Into Someone’s Eye Or Nose”

That close and obsessive reader, Tyler Cowen of the Marginal Revolution, posted this great passage from Kitty Burns Florey’s book, Script and Scribble: The Rise and Fall of Handwriting:

“There’s a popular myth that NASA spent ‘millions’ of dollars developing a pen for astronauts to use in the weightless environment of a space ship — while their sensible Russian counterparts were happy to use the low-tech pencil.  Alas, for all its appeal and plausibility, this is not true.  Initially, astronauts and cosmonauts were both equipped with pencils, but there were problems: if a piece of lead broke off, for example, it could float into someone’s eye or nose.  A pen was needed, one that would defy gravity, write in extreme heat or cold, and be leak proof: blobs of ink floating around the cabin would be more perilous than a stray pencil lead.  A long-time pen maker named Paul C. Fisher patented the ‘space pen’ in 1965 (which he had developed at the cost of a million dollars, at the request of but not under the auspices of NASA.)  NASA bought four hundred of them at $6 each, and, after a couple of years of testing, the pens were put into space.”
