On 21 Aug In 1888, William Seward Burroughs received U.S. patents on four adding machine applications. They were the first patents he held for his "Calculating-Machine" that he would continue to improve and successfully bring to market. He incorporated his business as the American Arithmometer Corporation in Jan 1886. After Burrough's early death in 1898, that company reorganized as the Burroughs Adding Machine Co., —its new name was in tribute to the inventor.

For those of us who reach for a cell phone or electronic calculator to do a quick sum, things have come a long way since Burroughs revolutionized the tedious manual calculations done by clerks in accounting and banking.

An extract from the book, The City of Detroit (1922) on the Burroughs Adding Machine gives some some human interest about what motivated him, his challenges in designing and marketing the equipment, and the eventual prosperity of the business which continued to grow after his death.

You may also take interest in an extensive biography of Benjamin Thompson, Count Rumford from Leading American Men of Science (1910), or, the controversial patent dispute won in the U.S. by William Kelly against Henry Bessemer's steel-making process. A Scientific American article (1857) reveals An English Opinion of the United States Patent Office Management is critical of the assignment of priority to Kelly whose winning claim was based on making his discovery before Bessemer, although Kelly failed to patent it in a timely way.

Quotations for Today
Thumbnail of Subrahmanyan Chandrasekhar
The pursuit of science has often been compared to the scaling of mountains, high and not so high. But who amongst us can hope, even in imagination, to scale the Everest and reach its summit when the sky is blue and the air is still, and in the stillness of the air survey the entire Himalayan range in the dazzling white of the snow stretching to infinity? None of us can hope for a comparable vision of nature and of the universe around us. But there is nothing mean or lowly in standing in the valley below and awaiting the sun to rise over Kinchinjunga.
— Subrahmanyan Chandrasekhar, Indian-American astronomer and astrophysicist (died 21 Aug 1995). quote icon

There is a genuine thirst for scientific knowledge in most homes. Satisfying that thirst will, I believe, create a friendly attitude toward science and scientists which will favor the cause of science in the future. Science needs an informed and friendly public to back it up.
[Stating the goals of his NBC TV show, Nature of Things, which first aired on 5 Feb 1948.]
— Roy K. Marshall, American astronomer (born 21 Aug 1907). quote icon

If what we are doing is not seen by some people as science fiction, it’s probably not transformative enough.
