Each of my mini wikipedia entries below has interest to me. I am not sure what to do with any, if at all but "thinking on blog" is the game of my Sunday mornings. Stay tuned...
Invented in 1943: From wikipedia: Aqua-Lung[1] was the original English name of the first open-circuit, self-contained underwater breathing apparatus (or "SCUBA") to reach worldwide popularity and commercial success. This class of equipment is now commonly referred to as a diving regulator[2] or demand valve. The Aqua-Lung was invented in Paris during the winter of 1942–1943 by two Frenchmen; the engineer Émile Gagnan and Naval Lieutenant ("lieutenant de vaisseau") Jacques Cousteau.

The Aqua-Lung was invented in Paris during the winter of 1942–1943 by two Frenchmen; the engineer Émile Gagnan and Naval Lieutenant ("lieutenant de vaisseau") Jacques Cousteau.In 1943, they made the film Épaves (Shipwrecks), in which they used two of the very first Aqua-Lung prototypes. These prototypes were made in Boulogne-Billancourt by the Air Liquide company, following instructions from Cousteau and Émile Gagnan.[2] When making Épaves, Cousteau could not find the necessary blank reels of movie film, but had to buy hundreds of small still camera film reels the same width, intended for a make of child's camera, and cemented them together to make long reels.[3][4]
Manufactured in 1943 (Designed in 1891): From wikipedia: The Mosin–Nagant (Russian: Винтовка Мосина, ISO 9: Vintovka Mosina) is a 5 shot, bolt-action, internal magazine-fed, military rifle, developed by the Imperial Russian Army in 1882–91, and used by the armed forces of the Russian Empire, the Soviet Union and various other nations. It is one of the most mass-produced military bolt-action rifles in history with over 37 million units produced since its inception in 1891, and much like the AK-47 it has shown up in various conflicts around the world, despite its age.
Died in 1943: From wikipedia: Nikola Tesla (Serbian Cyrillic: Никола Тесла; 10 July 1856 – 7 January 1943) was a Serbian American[3][4][5][6] inventor, electrical engineer, mechanical engineer, physicist, and futurist best known for his contributions to the design of the modern alternating current (AC) electricity supply system.[7]
Tesla gained experience in telephony and electrical engineering before immigrating to the United States in 1884 to work for Thomas Edison in New York City. He soon struck out on his own with financial backers, setting up laboratories and companies to develop a range of electrical devices. His patented AC induction motor and transformer were licensed by George Westinghouse, who also hired Tesla for a short time as a consultant. His work in the formative years of electric power development was involved in a corporate alternating current/direct current "War of Currents" as well as various patent battles. Tesla went on to pursue his ideas of wireless lighting and electricity distribution in his high-voltage, high-frequency power experiments in New York and Colorado Springs and made early (1893) pronouncements on the possibility of wireless communication with his devices. He tried to put these ideas to practical use in his ill-fated attempt at intercontinental wireless transmission, which was his unfinished Wardenclyffe Tower project.[8] In his lab he also conducted a range of experiments with mechanical oscillators/generators, electrical discharge tubes, and early X-ray imaging. He also built a wireless controlled boat, one of the first ever exhibited.
Tesla was renowned for his achievements and showmanship, eventually earning him a reputation in popular culture as an archetypal "mad scientist".[9] His patents earned him a considerable amount of money, much of which was used to finance his own projects with varying degrees of success.[10]:121,154 He lived most of his life in a series of New York hotels, through his retirement. He died on 7 January 1943.[11] His work fell into relative obscurity after his death, but in 1960 the General Conference on Weights and Measures named the SI unit of magnetic flux density the tesla in his honor.[12] Tesla has experienced a resurgence in interest in popular culture since the 1990s.[13]
