An ancient mechanical genius you may NOT know

We have all heard the great inventors of antiquity such as Archimedes and Hero. Here is another name worth knowing: Al-Jazari. Al-Jazari was an scholar, inventor, engineer, craftsman, artist, mathematician and astronomer from Mesopotamia, who lived from about 1136 to 1206. He wrote The Book of Knowledge of Ingenious Mechanical Devices, which describes some fifty sophisticated machines.

The video clip shown here from Ancient Discoveries covers Al-Jazari's elephant clock -- a fantastically elaborate device which employed automata. There are a working reproductions of the elephant clock in Dubai and Switzerland.

Here is the Wikipedia article for Al Jazari. Here is the article on the elephant clock.

Book: The Pneumatics of Hero of Alexandria

Hero (or Heron) of Alexandria (c. 10-70 AD) was a prolific inventor and mathematician and is one of the first known creators of automata in the history of Western civilization. His original works were destroyed in the fire that consumed the ancient library in Alexandria, but some of his work survived by way of copies that were made in Arabic. Here is his work on Pneumatics, which included a working steam engine -- an invention that was perhaps several thousand years ahead of its time.

Here is the book The Pneumatics of Hero of Alexandria

Birthday of Eli Whitney Jr., Inventor

There is a tribute on the Make Magazine Blog to this American inventor.

From the Make Blog:
"On this day in 1765, Eli Whitney, Jr. was born in Westborough, Massachusetts. Whitney would go on, most famously, to invent the cotton gin, which revolutionized cotton production in the antebellum South. He eventually became the most famous early American proponent of interchangeable parts, and also invented one of the world's first milling machines."

Here's the Make Magazine post about Eli Whitney.

Profile of inventor Dean Kamen

I had the great pleasure of seeing Dean Kamen speak in Boston once and got to shake his hand afterward. I let him know that he was on of my heroes in no uncertain terms. He was very gracious.

He is currently working on heat driven Stirling engines (see this model Stirling Engine I posted about not long ago). He's not just working on the engines, but some novel applications for their use. I can't wait to see what he comes up with.

Here's a nice long profile on Dean Kamen, a modern day inventor. Found via BoingBoing.net's coverage today.
