If you're interested in the history of scientists chasing cold, "Absolute Zero and the Conquest of Cold" by Tom Shachtman is an interesting read.
Beginning in 1620 when Cornelis Drebbel cooled Westminster Abbey, the book follows the exploration of lower & still lower temperatures, liquefying gasses, and some of the effects ultra-cold can have on various materials. The invention & refinement of the thermometer is covered along with the natural ice industry & commercial refrigeration.
Anyway... if you enjoy science history you may want to give this book a look.
