I have been sampling Herbert Hoover's memoirs and discovered that he was a very able man with a lively intellect. Pity that his presidency was obliterated by the Great Depression. Here is an excerpt from Chapter 9, Family Living and Extra-Curricular Activities 1908-1914:
"For some years I had been interested in the older literature of engineering and applied science generally. I had formed quite a collection of fifteenth and sixteenth century books on early science, engineering, metallurgy, mathematics, alchemy, etc. One of these — Agricola's De Re Metallica — a folio published in Latin in 1556, was the first important attempt to assemble systematically in print the world-knowledge on mining, metallurgy, and industrial chemistry. It was the great textbook of those industries for two centuries and had dominated thought and practice all that time. In many mining regions and camps, including the Spanish South American, it was chained to the church altar and translated by the priest to the miners between religious services. No one had ever succeeded in translating it into English, although several had tried. My own study of Latin had never gone beyond some elementary early schooling and a few intermittent attempts to penetrate further into that language and literature after I left college. Mrs. Hoover was a good Latinist after she brushed up a little, and we found we could work it out. The problem of the "untranslatable" Agricola fascinated us both, and finally in 1907 we resolved to translate it jointly. There were formidable difficulties; for while Agricola's Latin was scholarly enough, he was dealing with subjects the whole nomenclature and practice of which had developed hundreds of years after the Latin language ceased to grow. He did not adopt into the text the German, Italian or English terms for the operations or substances he described, but coined or adapted Latin terms for them. It was thus obvious why Latin scholars had failed in translation into English. It had been translated after a fashion into both German and French by persons unfamiliar with the arts described. For this reason, their work had failed also.
The job involved finding out — either from the context, from German, French, Italian, or other fragmentary literature of the times, or from study of the processes themselves — what he meant. Mrs. Hoover's ability to read German and some French helped greatly. Sometimes the task amounted more to scientific detective work than to translation. Material A might start as an unknown substance but in different parts of the book Agricola would state its varying reactions when treated or combined with known substances B or C. Thus I could often have the meaning of his terms worked out in our laboratories. Often enough, when we discovered the meaning of a term we found that there was no modern word to express it because that particular process had been long abandoned. In any event, we grappled with it sentence by sentence, during our spare time, month after month, for over five years. We lugged the manuscript all over the world for odd moments that would be available for work on it."
