  Cajori
Cajori held the chair of mathematics at Colorado College from 1898 until 1918, being Dean of the Department of Engineering for the last fifteen years of his time at Colorado Springs.
We must now examine a little of the contribution which Cajori made to the history of mathematics to understand his high international reputation in the subject which gained him many honours in his lifetime but the somewhat less regard in which he is held by historians of science today.
Cajori makes very clear his aim in producing this edition of Newton's Principia which was to make the text readable to modern readers by replacing the archaic language used in the existing English translations of Newton's Latin text.

 Professor Fauvel's Address
Inwardly Cajori would have found it particularly tiresome as he knew he would have to print this interpretation in the series of Colorado College Studies which he had founded thirteen years before, and whose academic standards he was attempting to keep high.
Cajori’s final years at the College must have been the most painful and stressful of his career, though that was nothing to do with the students.
Cajori’s leaving provoked one of the most moving editorials to have appeared in the Tiger, the Colorado College Newspaper of the time.

 Dollar sign
Not only is there no documentation to support this origin, but as Cajori points out, it flies in the face of the earliest recorded usage of the dollar symbol by a high US official.
Cajori shows a series of different notations between 1600-1800 from Spanish notes and ledgers that support the emergence of the $ symbol from this origin.
Cajori sights a document from 1778 with thirty-four subscribers to a theater, including George Washington.

 AUE: FAQ excerpt: Origin of the dollar sign
It is sometimes said that the dollar sign's origin is a narrow "U" superimposed over a wide "S", "U.S." being short for "United States." This is wrong, and the correct explanation also tells why the $ sign is used both for dollars and for pesos in various countries.
Cajori acknowledges the "U.S." theory and a number of others, but, after examining many 18th-century manuscripts, finds that there is simply no evidence to support those theories.
Cajori reproduces 14 $ signs from a diary written in 1776; 11 of them have the single stroke, which was the more common form to the end of the century, and 3 have the double stroke.

 Florian Cajori --  Encyclopædia Britannica
Cajori emigrated to the United States in 1875 and taught at Tulane University in New Orleans (1885–88) and at Colorado College (1889–1918), where he also served as dean of the department of engineering (1903–18).

 The Straight Dope: What does the S in the dollar sign represent?
Lord, if Florian Cajori were alive to hear such talk, it would just kill him.
Professor Cajori dealt with this question definitively more than 60 years ago in A History of Mathematical Notations--not the ideal beach book, maybe, but one I heartily commend nonetheless.
Professor Cajori contends that the dollar sign is an abbreviation for "pesos." Bear in mind that the Spanish dollar, also known as the peso de 8 reales, was the principal coin in circulation in the U.S. up until 1794, when we began minting our own dollars.

 Cajori - History of  the Logarithmic Slide Rule
The author was born in Switzerland but spent all his adult life as an academic in the United States.
Cajori suggested that slide rules were little used in the US until the final decades of the 19th century.
This addenda is critical as it is here that Cajori attributes the invention of the slide rule to Oughtred.

 Professor Florian Cajori   (Site not responding. Last check: 2007-09-07)
Florian Cajori (1859-1930) was born in Switzerland, son of a leading civil engineer, and came to the United States in 1875, when he was sixteen.
As professor of physics from 1889-1898, Cajori ardently promoted scientific studies at the college, not least through his founding of the Colorado College Scientific Society in 1890, and is celebrated particularly for taking, with his physics class, the first X-ray photographs in the West.
By the end of his time at the college his qualities of calm, reliable diplomacy proved invaluable when he chaired the gang of three who steered the college over the tumultuous period at the end of President Slocum's reign.

Thomas Harriot (1560-1621) was an English mathematician who lived the longer part of his life in the sixteenth century but whose outstanding publication appeared in the seventeenth century.
William Oughtred (1574-1660) contributed vastly to the propagation of mathematical knowledge in English by his treatises, the Clavis Mathematicae, 1631, published in Latin (English edition 1647), Circles of Proportion, 1632, and Trigonometrie, 1657.

According to Cajori (1906), the Latin term sinus was introduced in a translation of the astronomy of Al Battani by Plato of Tivoli (or Plato Tiburtinus).
Cajori gives Edmund Wingate the credit for devising the first slide rule in 1630, although William Oughtred’s device of 1632 is more often cited.
Cajori states that Oughtred was an independent discoverer of the rectilinear slide rule and the first to propose a circular rule.

 Physics Today On The Web - Book Review March 2000
Motte’s standard English translation from the Latin appeared in 1729, two years after Newton’s death, and by 1934 it was certainly archaic and in need of replacement.
For many years, scholars have recognized that Cajori’s revision of Motte’s translation was inadequate: It was awkward, often inaccurate, and it was based on the second and not the final (third) edition of the Principia.
Cohen and Whitman (who died in 1984, after the translation was completed) met the challenge and have produced an excellent, modern translation that is more accurate and easier to read than the Motte—Cajori version.
