Hermann Oberth, the German father of rocketry, has a mixed legacy. On the one hand, he developed the V-2 rocket for Nazi Germany during World II. On the other hand, his ideas, rejected as implausible when he submitted them as part of his doctoral thesis, paved the way for the development of rocketry, and he later helped launch the United States into space.

James Naismith was a Canadian physical education instructor who invented basketball in 1891. The first formal rules were devised in 1892. Initially, players dribbled a football ball up and down a court of unspecified
dimensions. Points were earned by landing the ball in a peach
basket. Iron hoops and a hammock-style basket were introduced in 1893. However,
another decade passed before the innovation of open-ended nets put an end to
the practice of manually retrieving the ball from the basket each time a goal
was scored. US Patent #1,718,305 was granted to G L Pierce on June 25, 1929 for
the "basketball" used in the game.

Éleuthère Irénée du Pont de Nemours known as Irénée du Pont, or E.I. du Pont, was a French-born American chemist and industrialist who emmigrated to the United States in 1799 and founded the gunpowder manufacturing business, E. I. du Pont de Nemours and Company. His descendants, the centuries Du Pont family, were one of America's richest and most prominent families in the nineteenth and twentieth.

On June 24 of the year 1873, U.S. Patent No.: 140,245 issued to Samuel L. Clemens for an "Improvement in Scrap-Books". Clemens is better known by his pseudonym, "Mark Twain", which was a meausure of water depth used by steamboat pilots on the Mississippi River to indicate two fathoms. In addition to being a well-known writer, humorist, publisher, and lecturer, Twain was an inventor who held three patents. The '245 patent was his second and, by far, his most successful patent.

Alan Turing was a
brilliant British mathematician who took a leading role in breaking Nazi
ciphers during WWII. In his seminal 1936 paper, he proved that there cannot
exist any universal algorithmic method of determining truth in mathematics, and
that mathematics will always contain undecidable propositions. His work is
widely acknowledged as foundational research of computer science and artificial
intelligence.
Early Life
English scientist Alan
Turing was born Alan Mathison Turing on June 23, 1912, in Maida Vale, London,
England. At a young age, he displayed signs of high intelligence, which some of
his teachers recognized, but did not necessarily respect. When Turing attended
the well-known independent Sherborne School at the age of 13, he became
particularly interested in math and science.
After Sherborne, Turing
enrolled at King's College (University of Cambridge) in Cambridge, England,
studying there from 1931 to 1934. As a result of his dissertation, in which he
proved the central limit theorem, Turing was elected a fellow at the school
upon his graduation.
In 1936, Turing
delivered a paper, "On Computable Numbers, with an Application to the
Entscheidungsproblem," in which he presented the notion of a universal
machine (later called the “Universal Turing Machine," and then the
"Turing machine") capable of computing anything that is computable:
It is considered the precursor to the modern computer.

Birthday of Dr.
Howard T. Engstrom – Promoter of Digital Computer
American computer designer who promoted the first
commercially available digital computer, the Univac. As a Yale professor he had
written a paper on the mathematical basis for cryptanalysis techniques. During
WW II he was called to the Navy and placed in command of the OP-20-G automated
machines "Research Section" for message decryption. After the war, he
was a co-founder of
Engineering Research Associates, a private company to work on electronic
digital circuit technology for the Navy on a contract basis, with former Navy
researchers. ERA delivered its
first Atlas computer to the National Security Agency in Dec 1950. As vice
president for research, Engstrom took the initiative to make a commercial
version, renamed Univac.
