Dr Laszlo Kreizler is the main character of the Kreizler series, a historical mystery novel series by Caleb Carr. The books have been adapted into a Netflix series titled The Alienist, where Dr Kreizler is played by Spanish-German actor Daniel Brühl.
László Cseh is a Hungarian competitive swimmer and six-time Olympic medalist. He is a 33-time European Champion. His father, László Cseh Sr., also represented Hungary at the Olympics in swimming.
Laslow (a variant spelling) is the name of a character from Fire Emblem: Fates. He is the same character as Inigo from Fire Emblem: Awakening, the previous game. (Laslow is the alias that Inigo is using in Nohr.)
"LASZLO!" Shouted Tallulah (three L's, one H), the annoyingly nasally showgirl (or whatever she was) in the Doctor Who episodes "Daleks in Manhatten" and "Evolution of the Daleks."

It's all so clear, now. Bill Joyce must be a Dr. Who fan. He named two of his characters Tallulah and Laszlo in his children's book, "A Day with Wilbur Robinson." Tallulah is Wilbur's older sister, while Laszlo is a cousin who has invented an anti-gravity belt. When the book was made into the Disney movie "Meet the Robinsons," Tallulah and Laszlo were made sister and brother (Grandpa Bud's niece and nephew). Added to Laszlo's belt was a paint gun that he proves himself quite skilled with.
Actually, after some research I've discovered it's the other way around. The creators of Doctor Who are clearly William Joyce fans. They took the names Tallulah and Lazlo and wrote an episode featuring the codifier of the name, Tallulah Bankhead (although she was in London in 1930, but that's historical license for you). It's what we tropers call Fridge Brilliance.
