Question: Who invented the gun where  The Blish Lock was first used?

Context paragraphs:
Thompson submachine gun: The Thompson submachine gun is an American submachine gun, invented by John T. Thompson in 1918, that became infamous during the Prohibition era.  It was a common sight in the media of the time, being used by both law enforcement officers and criminals.  The Thompson submachine gun was also known informally as the "Tommy Gun", "Annihilator", "Chicago Typewriter", "Chicago Piano", "Chicago Style", "Chicago Organ Grinder", "Trench Broom", "Trench Sweeper", "The Chopper", and simply "The Thompson".

Canon d'Infanterie de 37 modèle 1916 TRP: The Canon d'Infanterie de 37 modèle 1916 TRP (37mm mle.1916) was a French infantry support gun, first used during World War I.  "TRP" stands for "tir rapide, Puteaux" (fast-firing, designed by the "Atelier de Puteaux").  The tactical purpose of this gun was the destruction of machine gun nests.  It was also used on aircraft such as the Beardmore W.B.V and the Salmson-Moineau.  Fighter ace René Fonck used a 37mm mle.1916 on a SPAD S.XII.

Blish lock: The Blish Lock is a breech locking mechanism designed by John Bell Blish based upon his observation that under extreme pressures, certain dissimilar metals will resist movement with a force greater than normal friction laws would predict.  In modern engineering terminology, it is an extreme manifestation of what is now called static friction, or "stiction".  His locking mechanism was used first in the Thompson submachine gun.

John Bell Blish: John Bell Blish (September 8, 1860 – December 22, 1921) was an American inventor known primarily for developing the Blish lock, used in the Thompson submachine gun.  Blish licensed the patent for his lock to the Auto-Ordnance Corporation in 1915 in return for company stock.

9 cm Feldkanone M 75/96: The 9 cm Feldkanone M 75/96 was a field gun used by Austria-Hungary during World War I, a modernized version of the M 75 field gun.  Virtually all the M 76s were upgraded during 1898.  For cost reasons the new gun retained the bronze barrel of the original, although it was actually redesigned to withstand the more powerful propellants coming into use.  A touch hole lock was added to prevent accidental misfiring when the breech was open.  A spring-mounted spade brake reduced recoil from 5–6 metres to 80 centimetres, although it only worked if the spade was buried in the ground.  A depression lever was added to elevate the carriage's trail to allow the gun greater depression in mountainous areas.  Many guns had shields added after the outbreak of World War I.

Snap gun: A snap gun, also known as lock pick gun, pick gun, or electric lock pick, is a tool that can be used to force open a mechanical pin tumbler lock (a common type of cylinder lock) without using the key.  A steel rod is inserted into the lock and the snap gun briefly fires the rod against all of the lock pins simultaneously, momentarily freeing the cylinder and enabling it to be turned using a tension wrench.  The snap gun is an alternative to a conventional lockpick, which requires other techniques such as raking to free the pins.

Thompson Autorifle: The Thompson Autorifle was a semi-automatic rifle that used a Blish Lock to delay the action of the weapon.  It was chambered in .30-06, with the 1923 model in 7.62×54mmR Russian rifle rounds.

Gun safe: A gun safe is a secure and protective storage container for one or more firearms, and, or ammunition for those guns.  Gun safes are primarily used to prevent access to unauthorized or unqualified persons, for burglary protection, and, in more capable safes, to protect the contents from damage during a flood, fire, or natural disaster.  Access prevention is required by law in many places, necessitating a gun lock, metal gun cabinet, or gun safe.  Gun safes have largely replaced the gun cabinets made of fine stained wood with etched glass fronts used for display that were commonly used decades ago, although some gun safes are made to resemble such gun cabinets.

Boulter's Lock: Boulter's Lock is a lock and weir on the River Thames in England on the eastern side of Maidenhead, Berkshire.  A lock was first built here by the Thames Navigation Commission in 1772.  The lock is on the western side of the river between the main (A4094) Maidenhead to Cookham road and Ray Mill Island.  The name is also used for the immediate surrounding area.

Work–life balance: Work–life balance is a concept including the proper prioritization between work (career and ambition) and lifestyle (health, pleasure, leisure, family).  The work–leisure dichotomy was invented in the mid-1800s.  Paul Krassner, an American journalist, observed that anthropologists define happiness as having as little separation as possible between your work and your play.  The expression "work–life balance" was first used in the United Kingdom in the late 1970s to describe the balance between an individual's work and personal life.  In the United States, this phrase was first used in 1986.
