Keno Don Hugo Rosa, known simply as Don Rosa, (born June 29, 1951) is an American comic book writer and illustrator known for his stories about Scrooge McDuck, Donald Duck and other characters created by Carl Barks for Disney comics, such as The Life and Times of Scrooge McDuck, Son of the Sun and many others.

Don Rosa's grandfather, Gioachino Rosa, lived in Maniago, a town at the foot of the Alps in Northern Italy, in the province of Pordenone. He emigrated to Kentucky, United States around 1900, established a successful tile and terrazzo company, then returned to Italy to marry and start a family. In 1915 just after the birth of his son Ugo Rosa, Gioachino returned to Kentucky with his wife, two daughters and two sons. Ugo Rosa grew up and was later married in Kentucky. His wife was born to a German American father and a mother with both Scottish and Irish ancestry.

Don Rosa was born Keno Don Hugo Rosa on June 29, 1951 in Louisville, Kentucky. He was named after both his father and grandfather. Gioachino was called "Keno" for short. Don's father was named Ugo Dante Rosa, but used the name "Hugo Don" Rosa in America.

The name Rosa, Latin and botanic name of the flowering shrub Rose, could refer to:

Scrooge McDuck is a cartoon character created in 1947 by Carl Barks and licensed by The Walt Disney Company. Scrooge is an elderly Scottish anthropomorphic white duck with a yellow-orange bill, legs, and feet. He typically wears a red or blue frock coat, top hat, pince-nez glasses, and spats and is portrayed in animations as speaking with a slight Scottish accent, also sometimes known as a Scottish burr. His dominant character trait is his thrift, and within the context of the fictional Disney universe, he is the Earth's richest person.

Named after Ebenezer Scrooge from the 1843 novel A Christmas Carol, Scrooge is a wealthy Scottish business magnate and tycoon. He was in his first few appearances characterized as a greedy miser and antihero (as Charles Dickens' original Scrooge was), but in later comics and animated shorts and the modern day he is more often portrayed as a charitable and thrifty hero, adventurer, explorer and philanthropist. Scrooge was created by Barks as a comic book character originally as an antagonist for Donald Duck, first appearing in the 1947 Four Color story "Christmas on Bear Mountain" (#178). The character soon became so popular that McDuck soon became a major figure of the Duck universe. In 1952 he was given his own comic book series, called Uncle Scrooge, which still runs today. Scrooge was most famously drawn by his creator Carl Barks, and later by Don Rosa. Comics have remained Scrooge's primary medium, although he has also appeared in animated cartoons, most extensively in the television series Duck Tales (1987–1990).

William "Bill" Finger (February 8, 1914 – January 18, 1974)^{[citation needed]} was an American comic strip and comic book writer best known as the uncredited co-creator, with Bob Kane, of the DC Comics character Batman, as well as the co-architect of the series' development. In later years, Kane acknowledged Finger as "a contributing force" in the character's creation, and comics historian Ron Goulart has referred to Batman as the "creation of artist Bob Kane and writer Bill Finger". A DC Comics press release in 2007 stated that, "Kane, along with writer Bill Finger, had just created Batman for DC predecessor National Comics."

Finger additionally helped create Batman nemeses The Joker, The Penguin, Catwoman, Two-Face, The Riddler, and others. He also wrote many of the original 1940s Green Lantern stories and would go on to contribute to the development of numerous comic book series.

He was posthumously inducted into the comic book industry's Jack Kirby Hall of Fame in 1994 and the Will Eisner Comic Book Hall of Fame in 1999. His name provided the basis for the Bill Finger Award, founded by Jerry Robinson and presented annually at Comic-Con International to honor lifetime achievements by comic book writers insufficiently honored for their work in the medium.
