Max Friz (1 October 1883 – 9 June 1966) was a German mechanical engineer specializing in engine design. He was the key contributor of engine design and innovation that led to the founding of Bayerische Motoren Werke AG (BMW) in 1917.

Assumed to be originally from Urach, very little is known about Friz' youth. It is known however, that at a young age, he apprenticed to the Kuhn steam engine company in Cannstatt starting in 1898. In 1902 he enrolled at the Royal Building Trade School in Stuttgart-Esslingen furthering his engineering skills. In 1906 he was employed by Daimler Motoren Gesellschaft, in the Design Office, making major contributions to the design of the racing engine for the 1914 Mercedes Grand Prix car that won the French Grand Prix.

Friz designed the first practical German aircraft engines in 1912-1913 while at Austro-Daimler. The engines had separate cylinders on the crankcase and an overhead camshaft driven by a vertical shaft and bevel gears. At the end of 1916 the young engineer Max Friz applied for a position with Rapp Motorenwerke. At that time Friz was still working for the Daimler engine company in Untertürkheim, near Stuttgart. However, he was frustrated because the chief engineer, Paul Daimler, ignored the suggestions of his young assistant on engine development. Faced with this situation, Friz remembered his former colleague, Karl Rapp. At first Rapp was going to turn down Friz’s request; however, Josef Popp successfully intervened on Friz’s behalf, because he recognized that Rapp Motorenwerke lacked an able designer.

Isadore "Friz" Freleng (August 21, 1905 – May 26, 1995) was an animator, cartoonist, director, and producer best known for his work on the Looney Tunes and Merrie Melodies series of cartoons from Warner Bros.

He introduced and/or developed several of the studio's biggest stars, including Bugs Bunny, Porky Pig, Tweety Bird, Sylvester the cat, Yosemite Sam (to whom he was said to bear more than a passing resemblance) and Speedy Gonzales. The senior director at Warners' Termite Terrace studio, Freleng directed more cartoons than any other director in the studio (a total of 266), and is also the most honored of the Warner directors, having won four Academy Awards. After Warners shut down the animation studio in 1963, Freleng and business partner David H. DePatie founded DePatie-Freleng Enterprises, which produced cartoons (notably The Pink Panther Show), feature film title sequences, and Saturday morning cartoons through the early 1980s.

The nickname "Friz" came from how "frizzy" his hair was at one time. He began going by "Friz" during World War II, after having been credited as "I. Freleng", since the outbreak, after there had been concerns about his German-sounding name.

Leon Schlesinger (May 20, 1884 – December 25, 1949) was an American film producer, most noted for founding Leon Schlesinger Productions, which later became the Warner Bros. Cartoons studio, during the Golden Age of American animation. He was also a distant relative of the Warner Brothers.

Schlesinger was born in Philadelphia. After working at a theater as an usher, songbook agent, actor, and manager (including the Palace Theater in Buffalo, New York), he founded Pacific Title and Art in 1919, where most of his business was producing title cards for silent films. As talking pictures ("talkies") gained popularity in 1929 and 1930, Schlesinger looked for ways to capitalize on the new technology and stay in business. Some film historians claim that he helped finance the Warner brothers' first talkie, The Jazz Singer. He then secured a contract with the studio to produce its brand-new Looney Tunes series, and he signed animators Hugh Harman and Rudy Ising to create these cartoons with their Bosko character as the star.
