Well they mentioned Euler's connection to them. They ought to have mentioned Leibniz too (close friends and mentor to both Johann and Jacob at the 2nd row).

They backed Leibniz strongly over Newton regd the calculus dispute

(IMO largely Newton's fault from his bad bookkeeping and documentation, he loved to scribble things and forget about publishing them quickly).

(Daniel) Bernoulli came up early in uni for me regd fluid dynamics (his equation works quite well as long as the fluid is not being compressed too much). iirc though it was Euler that actually derived the final equation.

But I already knew Bernoulli family from childhood when Johann set the famous "least time" problem and Newton posted a very elegant solution anonymously (using calculus ofc that was source of much consternation, friction but also respect between the two sides)..... so much so that even though there was no name in this reply .... Bernoulli supposedly remarked "I know the lion by its paw!" (i.e Only Newton can be that good heh)

Trip down memory lane, thanks.

Tupolev - The Soviet Factory That Built 18,000 Aircraft - Vintage Aviation News

Founded by Andrei Tupolev in 1922, the design bureau created some of the Soviet Union’s most important bombers, airliners and strategic aircraft before becoming part of United Aircraft Corporation.

More than 100 types of aircraft, more than 18,000 planes, were designed and manufactured by a designer of civilian and military aircraft who influenced Russian and Soviet aviation. Andrei Tupolev founded the Tupolev OKB in 1922. In the 1920s, it developed all-metal airplanes based on Hugo Junkers’ work during WWI. In its early years, Tupolev made contributions to aviation with two important all-metal heavy bombers that had corrugated duralumin skins. The first was the ANT-4 twin-engine bomber, which first flew in 1925. The second was the four-engine ANT-6, introduced in 1932, from which aircraft like the ANT-20 were developed. The designs set important trends for the development of heavy aircraft in both military and civil aviation. During WWII, the twin-engine Tu-2 became one of the best bombers used by the Soviet Union. From 1942, several versions of the Tu-2 were produced in large quantities. Due to metal shortages during the war, some models had wooden rear fuselages. After the war, Tupolev developed the Tu-4, which was a copy of the American B-29 Superfortress. Then came the jet-powered Tu-16 bomber, designed with a swept-back wing to perform well at subsonic speeds. The Soviets wanted a long-range bomber. This led the company to develop the Tu-20 (called the Tu-95). It was a design based on the Tu-4 but with four large Kuznetsov NK-12 turboprop engines. The combination gave it both fast speeds and the ability to travel long distances.
