Linus Yale Sr. was an American inventor and manufacturer of locks.
Yale patented his cylinder pin-tumbler lock in 1861.
Pin-tumbler locks were originally invented in ancient Egypt. The design used a series of single pins that, when locked, would prevent movement of a bolt by resting inside the bolt itself. The key was used to raise pins out of the bolt, allowing it to retract.
The earliest patent for a double-acting pin tumbler lock was granted to American physician Abraham O. Stansbury in England in 1805, but the modern version, still in use today, was invented by American Linus Yale, Sr. in 1848.
Locks have been invented because people wanted to keep intruders out and their belongings safe. The oldest known door lock was made by the ancient Egyptians. Archaeologists found it in the Khorsabad palace ruins near Nineveh.

W. A. Martin - Lock
In 1889, W. A. Martin patented the lock. His invention was an improvement to the original invented by the Chinese over 4000 years old. It then paved the way to the design of modern door locks.
The locks are called Ancient Greek or Spartan locks and may have been considered a Greek invention. The Romans adopted the concept from Greece and began making locks of metal as well. Bronze key from the Artemis Hemera temple in Lusoi, Arcadia. The original is at the Museum of Fine Arts in Boston.
John Lee Love (?-1931)
Love spent his adult life working as a carpenter in Fall River, Massachusetts. In 1894, Love invented the hand-cranked pencil sharpener, a portable alternative to contemporary pencil sharpeners.
Sarah Boone was an American inventor best known for her patented improvements to the ironing board. She was one of the first African American women to receive a patent in United States history.
Thomas W. Stewart, an African American inventor from Kalamazoo, Michigan, patented a new type of mop (U.S. patent #499,402) on June 11, 1893. Thanks to his invention of a clamping device that could wring water out of the mop by using a lever, floor cleaning was not nearly the chore it once was.
Early history. The lock originated in the Near East; the oldest known example was found in the ruins of the palace of Khorsabad near Nineveh. Possibly 4,000 years old, it is of the type known as a pin tumbler or, from its widespread use in Egypt, an Egyptian lock.

The induced-fit model was first proposed by Koshland in 1958 to explain the protein conformational changes in the binding process. This model suggests that an enzyme, when binding with its substrate, optimizes the interface through physical interactions to form the final complex structure.
The canal lock was developed in China, and first used in Europe during the Middle Ages. Locks enable ships to go from one water level to another, thus making many more transportation routes possible.
The first mechanical recodable card lock was invented in 1976 by Tor Sørnes, who had worked for VingCard since the 1950s. The first card lock order was shipped in 1979 to Westin Peachtree Plaza Hotel, Atlanta, US.
In 1848, a 16-year-old African-American inventor named Osbourn Dorsey developed the patent for the first modern doorknob as we know today and the doorstoppers.
