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.

Dan Gerhard
Brown was born on June 22, 1964, in Exeter, New Hampshire. He
has a younger sister, Valerie (born 1968) and brother, Gregory (born
1974). Brown attended Exeter's public schools until the ninth grade. He
grew up on the campus of Phillips Exeter Academy, where his father,
Richard G. Brown, was a teacher of mathematics and wrote textbooks from 1968
until his retirement in 1997. His mother, Constance (née Gerhard), trained as a
church organist and student of sacred music.
Brown's interest in secrets and
puzzles stems from their presence in his household as a child, where codes
and ciphers were
the linchpin tying together the mathematics, music, and languages in which his
parents worked. The young Brown spent hours working out anagrams and crossword puzzles,
and he and his siblings participated in elaborate treasure hunts devised by
their father on birthdays and holidays. On Christmas, for example, Brown and
his siblings did not find gifts under the tree, but followed a treasure map
with codes and clues throughout their house and even around town to find the
gifts. Brown's relationship with his father inspired that of Sophie Neveu and Jacques Saunière in The Da Vinci Code,
and Chapter 23 of that novel was inspired by one of his childhood treasure
hunts.
After graduating from Phillips Exeter, Brown attended Amherst College,
where he was a member of Psi Upsilon fraternity.
He played squash, sang in the Amherst Glee Club, and was a writing
student of visiting novelist Alan Lelchuk.
Brown spent the 1985 school year abroad in Seville,
Spain, where he was enrolled in an art history course at the University of Seville. Brown graduated
from Amherst in 1986.

Brief history
The PIN Code system was introduced in
India by Shriram Bhikaji Velankar, who had served as an additional secretary in
the Union ministry of communications. Its implementation began from August 15,
1972, with the objective of simplifying the sorting of mails, speeding up mail
transmission and delivery.
The need for
such a system was realised due to the confusion resulting from the duplication
of names of various places across the country, the use of multiple languages to
write addresses, and different ways in which the name of a place could be
spelt. For example, in Tamil Nadu, names like Mettur and Aathur are very
common. PIN codes help postmen deliver the letters to right people.
Mr. Shriram
Bhikaji Velankar was a Sanskrit Pandit and a strong practitioner of Pali
language. He expired on 1st April 1999.
