Presidents of Purpose
February 20, 2012
Today, February 20, 2012, is
Presidents Day in the United States. This is a formal
holiday, scheduled as the third Monday of February, in honor of the first
US president,
George Washington, whose birthday on February 22 was formerly celebrated as a holiday. Although officially a holiday just for George Washington, this day has evolved to include
Abraham Lincoln, who had a separate holiday on his birthday, February 12.
Now, as a matter of
political correctness, if not national pride, it's considered that all US presidents are honored on this day. This approach has a definite advantage. You can imagine the possible proliferation of holidays, or at least the
political wrangling, were the US to survive a few more centuries and some factions thought that particular presidents merited their own holidays. However, as a practical matter, holidays don't have as much of an impact as they did decades ago. Now, most
employees have seen their
forty hour working week morph into 24/7 professions.
US citizens are among the few who can boast a continuous succession of forty-four leaders, principally because the creators of the
United States Constitution did a very nice job of designing a
government. Although the US Constitution has been besieged by
special interest groups (e.g., the
Eighteenth Amendment to the United States Constitution, which prohibited
alcoholic beverages, later repealed by the
Twenty-First Amendment), it's survived, and so has the US government.
Some individuals are skilled leaders, and some individuals are both skilled, and leaders. Four of the forty-four US presidents have had credentials in
science,
mathematics and
engineering. This does not quite balance against the twenty-four of whom who were
lawyers.[1] Nor does it compare favorably with
Israel, which can boast of a bona fide
Ph.D. chemist as
its first president.
The first US president with a technical flair was
Thomas Jefferson (1743-1826), the third US president. Jefferson was a prolific
inventor,
horticulturist,
paleontologist, and a
bibliophile. A variant of one of his inventions, a
cryptographic device, was used by the
United States Army as late as 1942 (see figure).

The
US Library of Congress, partially destroyed in 1812, was replenished in 1815 by Jefferson's personal library of 6,487 books. Jefferson founded the
University of Virginia near his home at
Monticello, and among his many correspondents was the
English chemist,
Joseph Priestley (1733-1804).
James Garfield (1831-1881), the twentieth U.S. President discovered a novel proof of the
Pythagorean theorem when he was a member of the
U.S. House of Representatives. The
construction of his proof is shown in the figure, from which the obvious solution
can be derived by equating the area of the
trapezoid to that of the
triangles.

The proof is made by equating the area of the trapezoid to the combined area of the triangles.
A high school student should be able to complete the proof when given this construction.

Herbert Hoover (1874-1964), the thirty-first U.S. President, best known as the president at the time of the
Great Depression, was trained as a
mining engineer. Hoover's wife was a
geologist and
Latin scholar, and the two Hoovers published the first English translation of
"De Re Metallica", a book published in Latin in 1556.
"De Re Metallica" was the primary source of information about
mining,
mineralogy and
metallurgy, well into the
nineteenth century. Illustrations from the book appear in two of my previous articles (
Polymer-Carbon Nanotube Composites, March 28, 2011 and
Boron Nanoribbons, January 11, 2012).
The last technically-credentialed president was
Jimmy Carter, 39th President of the United States from 1977 to 1981, whom I featured in a
previous article (A Technologist in the White House, December 1, 2006). Carter received a
Bachelor of Science degree from the
United States Naval Academy, and he took
graduate courses in
nuclear physics and
reactor technology at
Union College in
Schenectady, New York.
The purpose of this training was to prepare him for
command of a
nuclear submarine, but this career path was thwarted by the death of his father. At his father's death, Carter needed to take charge of the family business.
The
reactor accident at Three Mile Island, March 28, 1979, happened during Carter's presidency, so his education may have helped in his decision process. This brings up the interesting point that we presently have non-technical people running a country with a much larger technology base than in 1979.
Although he was not officially a member of the presidential elite, probably because his advanced age during the early years of the United States prevented an active life, I must mention
Benjamin Franklin. Franklin performed many fundamental experiments with
electricity, and he invented the
lightning rod and
bifocals.
Walter Isaacson, who wrote biographies of Franklin,
Einstein and, most recently,
Steve Jobs, wrote that Franklin was "the most accomplished American of his age and the most influential in inventing the type of society America would become."[3]
