Vacuum flasks: fulfilling a need

As seen on a plaque at Scienceworks in the House Secrets exhibit.

James Dewar invented the vacuum flask in 1892 to keep laboratory gases cold. Twelve years later, Reinhold Burger manufactured the Thermos to keep our picnic drinks hot.

A nice demonstration of the third of Peter Drucker’s seven sources of innovation.

Innovation based on process need.

Or, put another way, James Dewar scratched an itch; though he did play Edison to Reinhold Burger’s Sameul Insull.
