American comic book creator and writer Brian Michael Bendis. On the first book of the Ultimate Marvel imprint, Ultimate Spider-Man, which debuted in 2000, he collaborated with Bill Jemas and Mark Millar.

He also produced the Marvel storylines "Avengers Disassembled," "Secret War," "House of M," "Secret Invasion," "Siege," and "Age of Ultron."
He has received five Eisner Awards for both his work on numerous Marvel Comics series and his creator-owned work. Less influenced by comic books, he draws on the writing of David Mamet, Richard Price, and Aaron Sorkin. Additionally, he has experience in movies, video games, television, and teaching courses on graphic novels at Portland State University and University of Oregon. Words for Pictures: The Art and Business of Writing Comics and Graphic Novels, written by Bendis and published by Random House in 2014, is a book on comics.
(Here's a 15 minute interview with Brian, he talks about Miles among other stuff he has worked on if your interested)
Sara Pichelli is an Italian comic book artist best known for creating the Miles Morales version of Ultimate Spider-Man. Pichelli began her career in animation before transitioning to the comic book industry and working for IDW Publishing. She eventually joined Marvel Comics in 2008 after being identified during a global talent search. Pichelli was hired as the primary artist for the second volume of Ultimate Comics: Spider-Man, which debuted in September 2011, after contributing to a number of Marvel comics, including Namora. 2011 Eagle Award for Favorite Newcomer Artist went to Pichelli.
Pichelli began her career with Marvel Comics in 2008 with the short-lived title NYX: No Way Home. In 2009, she collaborated briefly with writer Kathryn Immonen on the television series Runaways. On the limited series X-Men: Pixie Strikes Back, she additionally collaborated with Immonen. Pichelli contributed artwork to one of the I Am An Avenger anthology series' stories before joining the team working on Ultimate Comics: Spider-Man beginning with issue #15, released in October 2010. Following the conclusion of that series, she contributed to the 2011 limited series Ultimate Fallout, where she created the initial representation of Miles Morales' Spider-Man in the Ultimate Marvel reality. Starting in September, Pichelli assumed regular art responsibilities on the relaunched Ultimate Comics: Spider-Man starring Morales as the lead character.
Brian Bendis was initially worried about the introduction of Miles Morales to the Marvel fandom stating in an email interview, with Inverse, how terrifying it was to introduce a character such as Miles to a well-established continuity with a massive readership. The Marvel fandom is massive and does not hesitate to tell anyone when they don't like something so this is a very understandable fear, especially when dealing with such a well liked and known character like spiderman.
He states in the interview that “It’s genuinely scary to put out something in the world that’s brand new,” Bendis says. “The extra added fear with Miles was that we were trying to be additive to Spider-Man. No one was asking for that. No one was going, ‘I wish Spider-Man was just a little bit something else.’ So changing something so drastic in the franchise is daunting. But we really believed in what we were doing. Anyone could wear the mask.”
I think it's amazing that even though he was worried, he still believed in what he was doing when it comes to the creation of Miles Morales. After only 12 years, Miles Morales is now the lead in an Oscar-nominated movie with hundreds of comic book issues. Additionally, Brian Bendis is still "unpacking" a variety of emotions, including appreciation.
"Gratitude on a scale I didn't know was possible," adds Bendis. "I have so many feelings about this that I am still unpacking. All of them good. But Miles hitting this cultural home run that is the accumulation of literally hundreds of writers and artists from all over the world all gathered around this idea we had is startling."
