On 31 Jul 1800, Friedrich Wöhler was born, the German chemist who co-discovered an element, but is best known for his landmark accomplishment as the first chemist to create an organic compound from purely inorganic substances. Thus he united two disciplines formerly regarded as totally independent. This “Biographical Sketch of Frederick Wöhler” from The Popular Science Monthly (1880) will not only give you a comprehensive insight into his life and career, but should also impress you with the appetite of nineteenth century popular magazine readers for substantial science content.


Book of the Day
The Periodic Table (Everyman's Library Contemporary Classics Series)

He was born on 31 Jul 1919, and is remembered as an Italian novelist, short-story writer and poet. but Primo Levi was also a chemist most of his professional life. As a memoirist, he is noted for his restrained and moving autobiographical account of and reflections on survival in the Nazi concentration camps. Today's book pick is: The Periodic Table (Everyman's Library Contemporary Classics Series), by Primo Levi, his most famous book. In it, Primo Levi uses the elements as metaphors to create a cycle of linked, somewhat autobiographical tales, including stories of the Piedmontese Jewish community he came from, and of his response to the Holocaust.

With 4.5 out of 5 stars from approaching 100 reviewers, if you do nothing more than read their comments on the Amazon site, this book is well worthy of your attention. Your Webmaster has read and recommends it as an exquisite diversion from chemistry into profound stories from an all-too-real life. It is the kind of book your bookshelf has been waiting for! Here is one of the reviews, which tells you why I think it is charming to read, just for its own value as a reviewer’s personal anecdote:

I'd give it 6 stars if I could. By Jae Brodsky. When I was 14, my high school chemistry teacher gave my class a writing assignment, which really pissed us off. We were in a chemistry class, why did Mr. Ellison expect us to write a short story? It wasn't actually an entire story: the first half was already written for us. It was about the ‘adventures’ of one atom of carbon. I felt like I was reading a book for small children on molecular chemistry because the writing style was simple, with no extra flourishes and long, scientific phrases. How demeaning to 14 year old me! In any case, I went home and wrote a completely uninspired ending to the carbon-atom fairy tale. If I remember correctly, the rest of the class did the same thing. Some were better than others, but none of them even began to come close to the original ending.

Mr. Ellison took our mediocre stories and, in a bargain where we definitely got the better deal, gave us the end of Primo Levi's Carbon, the last chapter of The Periodic Table. Nothing had prepared me for it. That simple style that I had so despised the night before was in fact the work of a writer who had stripped off all of those unnecessary phrases that I had been looking for, who had left nothing but the unadorned truth. Struck by this, I went out and bought the book.

It consists of 21 chapters, each of which have an element of the periodic table as their themes. But in truth each chapter/story is based on one idea which is explored. Some stories are pure fiction, some are remembrances, and some are meditations. They range from family gatherings to amusing teenage chemistry mistakes to the threads that bind us all together. Levi was not only a gifted chemist and a gifted writer, but someone who had that rare talent of opening his personal philosophies to the reader, and you can't help but feel that you’ve gotten to know him by the end of the book, which certainly makes the read worth it.

It is available from Amazon, typically about New from $7.88. Used from $2.05. (As of earlier time of writing - subject to change.)


Quotations for Today
Thumbnail of Theobald Smith
No research will answer all queries that the future may raise. It is wiser to praise the work for what it has accomplished and then to formulate the problems still to be solved.
— Theobald Smith, American pathologist and microbiologist (born 31 Jul 1859). quote icon
Thumbnail of Primo Levi
Our atom of carbon enters the leaf, colliding with other innumerable (but here useless) molecules of nitrogen and oxygen. It adheres to a large and complicated molecule that activates it, and simultaneously receives the decisive message from the sky, in the flashing form of a packet of solar light; in an instant, like an insect caught by a spider, it is separated from its oxygen, combined with hydrogen and (one thinks) phosphorus, and finally inserted in a chain, whether long or short does not matter, but it is the chain of life. All this happens swiftly, in silence, at the temperature and pressure of the atmosphere, and gratis: dear colleagues, when we learn to do likewise we will be sicut Deus [like God], and we will have also solved the problem of hunger in the world.
— Primo Levi, Italian chemist and writer (born 31 Jul 1919). quote icon

I tell young people to reach for the stars. And I can't think of a greater high than you could possibly get than by inventing something.
— Stephanie Kwolek, American chemist and inventor (born 31 Jul 1923). quote icon

Births
Thumbnail of Theobald Smith
Theobald Smith, born 31 Jul 1859, was an American microbiologist and pathologist who discovered the causes of several infectious and parasitic diseases. He is often considered the greatest American bacteriologist. In 1892 he linked Texas cattle fever with a protozoan parasite spread by blood-sucking arthropods. At the time, many scientists were skeptical that disease would be spread by bloodsucking insects. However, the precedent was established for other scientists to make links in cases of other diseases spread by insects.
Which insect did Smith identify in the spread of Texas Cattle Fever?
Thumbnail of Friedrich Wöhler
Friedrich Wöhler, born 31 Jul 1800, was a German chemist who co-discovered a new element. Having studied first medicine, then mineralogy, it was chemistry that became his primary interest. He found a method in 1827 for the production of metallic aluminum in the form of a grey powder by heating aluminum chloride with potassium. In 1828, he succeeded in the isolation of beryllium as a black-grey powder as well as of yttrium and (1856) crystalline silicon. His is most well-known for the synthesis of urea from ammonium cyanate (1828), which created an organic compound from an inorganic one, showing there was no absolute distinction between the two areas of chemical study. In 1862, he produced acetylene from calcium carbide.
Not named above, can you identify another new element he co-discovered?
Thumbnail of Stephanie Kwolek
On 31 Jul 1923, Stephanie Kwolek was born, an American chemist who worked in DuPont’s textile fibers department. She invented a new high-performance fiber that would be acid- and base-resistant and stable at high temperatures, suitable to replace steel in radial tyres. In fact, the fibre she developed was five times stronger than steel and had half the density of fiberglass. It is used to make bullet-proof jackets, military helmets, aircraft parts, inflatable boats, gloves, rope, and building materials.
What is the name of the fiber that Kwolek invented?
Deaths
Thumbnail of Francis Edgar Stanley
Francis Edgar Stanley (1849-1918) was an American inventor, who with his twin brother Freeman, were famous manufacturers of automobiles. Francis previously had invented a photographic dry-plate process (1883), and as the Stanley Dry Plate Company the brothers had engaged in the manufacturing of the plates. They sold the company to Eastman Kodak in 1905, as their interest had turned to automobiles. At racing events, they often competed successfully against gasoline powered cars.
What powered the engines of Stanley cars?

On 31 July 1790, the first U.S. patent was granted to Samuel Hopkins of Vermont for a process for making potash and pearl ashes. Potash was used as an ingredient in soap and fertilizer. The patent was granted for a term of 14 years and signed by George Washington.
When this patent was issued, what number was printed upon it?

On 31 Jul 1910, a murderer and his mistress were arrested after the first use of Marconi radio telegraph signals in a murder case. The man was fleeing after murdering his wife in England. They were spotted on board a ship making a transatlantic voyage. It was the first ship to be fitted with radio-telegraph, and the Captain first used it on 22 Jul 1910 to notify London Police of his “strong suspicions.” The suspects were apprehended when the ship docked in Canada.
What was the name of this infamous murderer?
