THE FIRSTS: The word ‘scientist’ (1834)

Scientist, by any other name…

History of science is, unfortunately, not among the mandatory classes required for earning a diploma that allows oneself to be called a scientist. Worrisomely, nor is Logic as a formal class. All the more the pity because in the Middle Ages, when the word science entered the English language, to have scientific knowledge meant you have arrived at it by following the Aristotelian way of logical reasoning (a.k.a deductions and inductions). To be fair, the word existed already in Romance languages with the same meaning: new knowledge obtained by applying the rules of Aristotelian syllogisms. By the way, Aristotle is also the guy to whom we owe the basis of the scientific method, but that’s a story for another day.

Although words like scientific or science were altogether frequently used with regards of the scholarly endeavors of the ladies and gentlemen of the early 19th Century (yes, there were ladies too that dabbled into the sciences, even if sometimes it was only to write about the spectacular discoveries and controversies of their time), the term scientist has been officially coined in 1834 by William Whewell. A man truly blessed in the art of words, being credited with coining a lot of other famous words like anode and physicist, he proposed the word in a review of a science popularization book written by one Mrs. Somerville. The circumstance of how this came to be is masterly imparted to us by Sydney Ross in a superb historical account of the word scientist, published in 1962.

For the rounded scientist or for the merely curious, I truly recommend the lecture of the referenced papers. They’re delightful!

P.S. I checked and Wikipedia is correct with the following statement:

“To be exact, the person coined the term scientist was referred to in Whewell 1834 only as “some ingenious gentleman.” Ross added a comment that this “some ingenious gentleman” was Whewell himself, without giving the reason for the identification. Ross 1962, p.72.”

Even if, by some very slim chance, the “ingenious gentleman” was not Whewell himself, Whewell did propose the term scientist in a more formal manner six years later in 1840 bringing more than just linguistic justifications, like the diversity of those engaged in scientific endeavors and how they don’t call themselves natural philosophers anymore.

The FIRSTS: Adult neurogenesis (1962)

I am starting a new category today: the Firsts. It will feature articles that showed something really interesting for the first time. Yes, all articles show something for the first time, that’s why they are published. But I have noticed either a lack of acknowledgment (“it is known that x”) or a disregard for the old papers (“doesn’t count if it’s before, say, 2001”), particularly among the new generation of scientists. So I will feature both the really big ones (e.g., first proof of adult neurogenesis) or the more obscure, but nonetheless, first in their field (e.g., first synthesis of morphine).

Today, first proof of adult neurogenesis. Altman (1962) wanted to see the kinetics of glial proliferation after brain injury. Glial cells are the other type of cells in the brain and they outnumber the neurons 10 to 1. Altman lesioned the rat lateral geniculate nucleus (a portion of the thalamus that deals primarily with vision) and then injected the rats with thymidine-H3, a dye that labels the newly formed cells. In addition to the expected glial proliferation, he also observed (by microscope and careful histology) that some neurons were also stained with the dye, which means that they were born after the injection. The new neurons were in many regions of the brain (so not only those associated with the lesioned area), including the cortical areas.

Altman followed up and three years later published the first comprehensive study of postnatal (not adult) neurogenesis in dendate gyrus of the hippocampus.
