On 2 Apr 1814, Erastus Brigham Bigelow was born, an American industrialist, who developed power looms for making lace and many types of carpet. He invented his first loom for making coach lace at the age of 23.

He was a member of the committee that founded the Massachusetts Institute of Technology (MIT).

This short biography from A History of American Manufactures (1866) describes him as one of the "most eminent of American inventors."


Book of the Day
The Pencil: A History of Design and Circumstance

On 2 Apr 1827, Joseph Dixon began the manufacturing of lead pencils in the U.S.at his factory in Salem, Mass. Dixon was responsible for the development of the graphite industry in the U.S. Today's book pick is: The Pencil: A History of Design and Circumstance, by Henry Petroski, who is one of your Webmaster’s favorite authors. Any of his books are mind-sharpening to read, because his talent for fine writing comes with a deep knowledge of engineering and technology. In this book, Petroski traces the evolution of the pencil through the Industrial Revolution, when machine manufacture replaced earlier handwork. Along the way, he looks at some of pencil making’s great innovators. One of those was Henry David Thoreau, the famed writer. He worked in his father’s pencil factory, inventing techniques for grinding graphite and experimenting with blends of lead, clay, and other ingredients to yield pencils of varying hardness and darkness. If you thought the pencil could never be the subject to fill a book, Petroski will pleasantly surprize you!

[It would not be long] ere the whole surface of this country would be channelled for those nerves which are to diffuse, with the speed of thought, a knowledge of all that is occurring throughout the land, making, in fact, one neighborhood of the whole country.
— Samuel F. B. Morse, American artist and inventor (died 2 Apr 1872). quote icon
Thumbnail of Paul Joseph Cohen
To the average mathematician who merely wants to know his work is securely based, the most appealing choice is to avoid difficulties by means of Hilbert's program. Here one regards mathematics as a formal game and one is only concerned with the question of consistency ... . The Realist position is probably the one which most mathematicians would prefer to take. It is not until he becomes aware of some of the difficulties in set theory that he would even begin to question it. If these difficulties particularly upset him, he will rush to the shelter of Formalism, while his normal position will be somewhere between the two, trying to enjoy the best of two worlds.
— Paul Joseph Cohen, American mathematician (born 2 Apr 1934). quote icon
