# Deadmau5

Joel Thomas Zimmerman (born January 5, 1981), known professionally as deadmau5 (pronounced "dead-mouse"), is a Canadian electronic music producer and DJ. Zimmerman has received seven Grammy Award nominations for his songs. He mainly produces progressive house and electro house music, though he also produces and DJs other genres of electronic music, including techno under the alias Testpilot.

He has also collaborated with Steve Duda as the duo BSOD (Better Sounding On Drugs) and the band WTF? with Duda, Tommy Lee and DJ Aero. In 2007, he founded his own record label, Mau5trap. Deadmau5 later formed electronic music supergroups such as Kx5 with Kaskade and Rezzmau5 with Rezz. Zimmerman is currently one of the highest-paid electronic music producers in the world.
Zimmerman first gained recognition for his breakthrough 2008 album Random Album Title, which was certified gold in Canada and silver in the United Kingdom. The album included seminal releases "Faxing Berlin", "Not Exactly", and moderate chart hit "I Remember" (with Kaskade). In 2009, his fourth studio album For Lack of a Better Name was released to critical acclaim, featuring "Ghosts 'n' Stuff" (featuring Rob Swire), "Hi Friend" (featuring MC Flipside), and the critically acclaimed "Strobe".

In 2012, Zimmerman released singles "The Veldt" and "Professional Griefers" (featuring Gerard Way) to commercial success. These singles were featured on his sixth studio album, Album Title Goes Here. Following his departure from long-time label Ultra Records, Zimmerman released his seventh studio album, While(1<2), through Astralwerks and Virgin EMI in 2014. The album's release was supported by its four singles; "Avaritia", "Seeya" (featuring Colleen D'Agostino), "Infra Turbo Pigcart Racer", and "Phantoms Can't Hang".

## Early life

Zimmerman was born on January 5, 1981 in Niagara Falls, Ontario, Canada. His mother, Nancy (née Johnson), is a visual artist, and his father, Rodney Thomas "Rod" Zimmerman, is a General Motors plant worker. He has two siblings, Jennifer (older) and Chris (younger). His ancestry includes German, Swiss, and English heritage. He received his first keyboard for Christmas when he was a teenager. His music career began in the late 1990s, with a chiptune and demoscene movements-influenced sound with the Impulse Tracker.
Zimmerman graduated from Westlane Secondary School in Niagara Falls. He then worked with an online music licensing company and as a programmer. He adopted the name Deadmau5, which referred to a dead mouse he found in his computer; the unique spelling was a result of a maximum character limitation.
His early musical work was largely done in his mom's Niagara Falls basement. He later moved to a small apartment in Toronto.

The same month, Zimmerman left longtime label Ultra Records and signed with record label Astralwerks, a famed NYC-based imprint that houses artists such as Swedish House Mafia, David Guetta, and The Chemical Brothers.

## Personal life

They both have several matching tattoos, including the numbers "289m3d22h" on both of their arms, a sentimental reference to the day when they met, as well as two black stars underneath their eyes.

## Etymology

Zimmerman's father claims that when his son was in his early teens, he was chatting with a friend on his computer, which then abruptly shut off. According to Zimmerman's father, he said that it had a smell of burnt wire and had a strange odor. Zimmerman started to dismantle his computer and happened to find a dead mouse. Zimmerman then became known as the "dead mouse guy" among friends. He tried to change his name to "Deadmouse" in an online chat room, but it was too long, so he shortened it to "Deadmau5". "Maus" is the German word for "mouse" and is pronounced the same as in English; the ending character 5 instead of an 's' is a form of leet.
Zimmerman created the original logo—called the "mau5head"—while learning how to use 3D modelling software. The logo appears in many different colors and designs, and has been shown on the cover art of most of Zimmerman's albums. He was given the idea to wear a helmet based on the logo by one of his friends, Jay Gordon of the industrial metal band Orgy. In an interview with CBC Television, Zimmerman said that he wants his logo to be an "icon". Fans often attend Deadmau5 concerts sporting their own copy or alteration of the mau5head.
He created his website and began uploading songs to SectionZ and producing under the alias "Deadmau5" in 2002.

## Controversies
### DirtyCircuit

In 2008, an artist called DirtyCircuit claimed to have been threatened with legal action after using a sample called "LP_Faxing Berlin C_128bpm" that came bundled with FL Studio, and to which Zimmerman claimed copyright. The sample was a direct clip of a full bar of the song. Zimmerman provided a "Demo Track" which came bundled with FL Studio, along with several loop samples. The case caused slight discomfort among the users of FL Studio, and some have pointed out potential inconsistencies in the EULA of the software. Subsequent versions, after FL Studio 8, no longer contained those loop samples.

### Disney trademark dispute

In a 2012 interview with Rolling Stone, Zimmerman acknowledged possible similarities between his Mau5head logo and that of Mickey Mouse, joking that "someone at the Disney patent office fell asleep on that one."
In March 2014, it was reported that The Walt Disney Company had filed a request with the United States Patent and Trademark Office to investigate Zimmerman's application to register the Mau5head emblem as a trademark, noting its resemblance to the figure of Mickey Mouse. Disney officially filed its opposition in September 2014, arguing that the mark is likely to cause confusion because it is "nearly identical in appearance, connotation, and overall commercial impression" to Disney's trademarked iconography of Mickey Mouse. In response to the opposition, Zimmerman spoke out against Disney on Twitter, arguing that the company thinks of people as being "stupid" because "[they] might confuse an established electronic musician/performer with a cartoon mouse." Zimmerman also believed that he had been targeted by Disney due to their attempts to "cash in" on the EDM market, specifically alluding to Dconstructed—a recently released compilation album containing remixes of music from Disney properties by major electronic musicians such as Armin van Buuren, Avicii and Kaskade.
On September 4, 2014, Zimmerman revealed on Twitter that Disney had used "Ghosts 'n' Stuff" in a Mickey Mouse "re-micks" video (as part of Have a Laugh!) on their website and YouTube channel without his or his labels' permission, and posted pictures showing a takedown notice that had been sent to Disney by his lawyers. The letter also contained a trademark infringement accusation, arguing that the use of Deadmau5's name in material regarding the video falsely implied his endorsement of it. Disney argued that it had properly licensed the song and that there was "no merit to his statement."
In an October 2014 USPTO filing, Zimmerman argued that Disney has attempted to co-exist with him in goodwill. Zimmerman presented evidence that Disney had been in contact with him regarding potential collaborative projects, including an offer to participate in a "re-imagining" of Fantasia as a live concert tour for the film's 75th anniversary.
In June 2015, Zimmerman's attorney stated that he and Disney had "amicably resolved their dispute." Zimmerman appeared in an episode of the Disney+ series The Muppets Mayhem in 2023.

### Meowingtons trademark dispute

In 2015, Zimmerman attempted to register a trademark for the name of his pet cat, Professor Meowingtons, whom he adopted in 2010 and has incorporated into some of his own merchandising. However, the registration was rejected due to a pre-existing Meowingtons trademark held by an online retailer of the same name established in 2014, which sells cat-themed accessories and clothing. After discovering the trademark, Zimmerman petitioned against it, citing his pre-existing uses.
In March 2017, Zimmerman was sued by Emma Bassiri (the owner of the website) for trademark infringement and unfair competition; the suit argued that claims by Zimmerman that she had named the site specifically after the cat was false. Zimmerman himself told The Hollywood Reporter that "from the very beginning I was working to find a way to resolve this situation amicably", but that he had been forced to "litigate this woman out of existence". On May 15, 2017, Deadmau5 filed a countersuit against Bassiri with the intention of seeking forfeiture of Bassiri's website and domain name.
In March 2018, World Intellectual Property Review reported that Zimmerman and Bassiri had resolved their dispute.
Professor Meowingtons died in 2023, aged 16.

### Offensive remarks

In October 2018, Zimmerman posted comments on Twitter during an argument including the statements "I'll bet you suck a guy off for 40 grand, zero fucking questions asked" and "women don't possess penises". These comments were construed by readers as being homophobic and transphobic. Zimmerman apologized for his comments, saying that he "wasn't trying to make blatant transphobic statements", and had "just got into a heated argument with some dude online", noting that his comments had been taken "somewhere unintended".
A few days later, during a gaming stream, he referred to a track by fellow electronic artist Slushii as "AIDS fucking music" and calling it "autistic shit". Slushii – who is on the autism spectrum – responded to these comments on Twitter, calling them "really disappointing". Zimmerman later apologized for these comments, citing mental health issues that required "professional help", and stating that he would take time "off the radar" to "work on [himself]".
In February 2019, while playing PlayerUnknown's Battlegrounds on a livestream on Twitch, Zimmerman called another player a "fucking cock-sucking stream sniper fag." Twitch suspended Zimmerman from their platform for hate speech, after which he posted: "I know who I am, and I don't have to fucking sit here and cry and defend my fucking self with the obligatory 'I'm not that person, I am sorry' reflex," vowing to never work with the company again. Zimmerman later apologized for his remarks in a Reddit post, and was subsequently reinstated.
