Steve Hiroyuki Aoki (born November 30, 1977) is an American electro house musician, record producer and the founder of Dim Mak Records.

Steve Hiroyuki Aoki was born in Miami and grew up in Newport Beach, California. He graduated from Newport Harbor High School in 1995; he was a star player on the varsity badminton team. He is the third child of Rocky Aoki and Chizuru Kobayashi. His father was a former Japanese Olympic wrestler who also founded the restaurant chain Benihana. He has two older siblings, sister Kana (who is sometimes called by her middle name "Grace"), and brother Kevin (owner of Doraku Sushi restaurant).

As a child, Steve lived with his grandfather,^{[citation needed]} his mother, and his two older siblings.

Aoki attended the University of California, Santa Barbara and graduated with two B.A.s; one in Women's Studies and the other in Sociology. In college, he produced do-it-yourself records and ran underground concerts out of his Biko room in the Santa Barbara Student Housing Cooperative, which was located in Isla Vista, a section of residential land adjacent to UCSB. As a concert venue, the apartment became known as The Pickle Patch. By his early 20s, Aoki had built his own record label, which he named Dim Mak after his childhood hero, Bruce Lee. He has also been in numerous bands, including This Machine Kills, which released an album on Ebullition Records, Esperanza, and The Fire Next Time.

Eric Sheridan Prydz (born July 19, 1976) is a Swedish DJ and producer based in London, United Kingdom. The pronunciation of his surname is often questioned; it is pronounced "prids", but when under his alias, Pryda, it is pronounced "pride-ah". In October 2011, DJ Magazine announced the results of their annual Top 100 DJ Poll, where Prydz placed at #46.

Until recently, Prydz had only played shows in and around Europe as he has a fear of flying. In December 2008, Prydz was forced to cancel several dates in Australia, New Zealand and Malta after panic attacks prevented him from boarding the outbound flight.

On Armin van Buuren's radio show "A State of Trance" in February 2011, it was announced that Prydz recently became a father.

His debut live show called "EPIC" (Eric Prydz in Concert) was held on April 2nd, 2011 at the O2 Brixton Academy Arena in London where he played most of his own production, as well as unfinished and upcoming tracks. The second show was at Global Gathering on July 29th and the third instalment at the Alexandra Palace on November 26th.

George Francis FitzGerald (3 August 1851 – 22 February 1901) was an Irish professor of "natural and experimental philosophy" (i.e., physics) at Trinity College in Dublin, Ireland, during the last quarter of the 19th century.

FitzGerald was born at No. 19, Lower Mount Street in Dublin on 3 August 1851 to the Reverend William FitzGerald and his wife Anne Francis Stoney. Professor of Moral Philosophy in Trinity and vicar of St Anne's, Dawson Street, at the time of his son's birth, William FitzGerald was consecrated Bishop of Cork, Cloyne and Ross in 1857 and translated to Killaloe and Clonfert in 1862. George returned to Dublin and entered Trinity as a student at the age of 16. He became a Fellow of Trinity in 1877 and spent the rest of his career at this college.

Along with Oliver Lodge, Oliver Heaviside and Heinrich Hertz, FitzGerald was a leading figure among the group of "Maxwellians" who revised, extended, clarified, and confirmed James Clerk Maxwell's mathematical theories of the electromagnetic field during the late 1870s and the 1880s.
