Ellis D Fogg was the pseudonym of the Australian artist Roger Foley (born 24 January 1942).
 Now known as Roger Foley-Fogg, the National Film and Sound Archive have described him as Australia's "most innovative lighting designer and lumino kinetic sculptor."
 And Albie Thoms founder of friendly rival Lightshow group UBU said: ... "Fogg is later recognised as Sydney's leading lightshow artist" The term Lumino Kinetic Art was first used in 1966 by Frank Popper, Professor of Aesthetics at the University of Paris.
Leutnant Werner Voss (13 April 1897 – 23 September 1917) was a friendly rival of World War I's leading ace, Manfred von Richthofen.
 Richthofen himself considered Voss as the only pilot with the potential to exceed Richthofen's aerial victory score.
 When Voss was killed in action, he had scored 44 victories.
 As can be seen by the list below, his victory roll is well documented.
Miles Edgeworth, known as Reiji Mitsurugi (御剣 怜侍 一 , Mitsurugi Reiji ) in original Japanese language versions, is a fictional prosecutor in Capcom's "Ace Attorney" video game series.
 Initially introduced as a cold-hearted perfectionist, he appears as an antagonistic rival to main character Phoenix Wright in "".
 Following the events of the first game, the character has a change of heart and reappears as a friendly rival in most of the subsequent titles in the series.
 Due to the character's popularity, Edgeworth went on to star in two of his own spin-off games, "" and its sequel.
 Edgeworth has also made appearances in extended "Ace Attorney" media, such as film and animation, as well as several cameo appearances in titles outside of the main "Ace Attorney" series.
Infestation is the seventh studio album by American heavy metal band Ratt.
 It is the band's first original effort since their self-titled album in 1999.
 It marks the Ratt studio debut for guitarist Carlos Cavazo, formerly of Quiet Riot, and is also the final album to feature bassist Robbie Crane, as then-former bassist Juan Croucier rejoined the band in 2012.
 It was released by Loud & Proud via Roadrunner Records, a then-sub-label of their longtime home Atlantic Records.
 This is the first album since the death of Robbin Crosby in 2002.
Marcus Annius Verus ( 50 – 138 AD) was the grandfather and adoptive father of the Roman Emperor Marcus Aurelius, and father-in-law of Emperor Antoninus Pius.
 He was prefect of Rome and was enrolled as a patrician when Vespasian and Titus were censors.
 Verus was three times consul.
 The first time as a suffect in 97, then as ordinary consul in both 121 and 126.
 This is apparently the cause for a "very strange inscription, found on a large marble tablet excavated in the sixteenth century at St. Peter's in Rome" which alludes to this achievement while celebrating his skill "playing with a glass ball".
 Edward Champlain notes it was likely the creation of a friendly rival, Lucius Julius Ursus Servianus, who also held the consulate three times the last after Verus.
 One explanation is that the whole thing is a joke, based on the connection between Verus' known passion for playing ball and the notion of the ball game as political juggling: an elegant, self-deprecating and rather bitter joke, one not wholly complimentary to Verus.
 The aged L.Iulius Servianus wrote the piece himself, had it engraved on a marble slab - perhaps accompanying it with the statue of a toga-clad bear playing ball?
 - and had it delivered to M.Annius Verus on the Kalends of January, 126.
 When next they met, the two old men affected to laugh heartily at the joke.
 Fantasy perhaps, but this is a very strange inscription.
Robbinson Lantz Crosby (August 4, 1959 – June 6, 2002) was an American guitarist who was a member of glam metal band Ratt, earning several platinum albums in the US in the 1980s.
 Crosby died in 2002 from a heroin overdose and pneumonia with complications from AIDS.
Ratt is an American heavy metal band that had significant commercial success in the 1980s, with their albums having been certified as gold, platinum, and multi-platinum by the RIAA.
 The group is perhaps best known for hit singles such as "Round and Round" and "Lay It Down", tracks that ranked on Billboard's top 40 at No. 12 and No. 40, respectively, as well as other songs such as "Wanted Man", "You're in Love" and "Dance".
 Along with groups such as friendly rivals Mötley Crüe, Ratt has been recognized as instrumental in the formation of the early 1980s Los Angeles glam metal scene, also known as "hair metal" or "pop metal".
"Dance" is a song by American heavy metal band Ratt.
 It is the first track off their 1986 album "Dancing Undercover" and the tenth track of their compilation album "Ratt & Roll 81-91".
 It reached #59 on the Billboard Top 100.
 The song was written by Stephen Pearcy, guitarists Robbin Crosby and Warren DeMartini, and album producer Beau Hill.
"Wanted Man' is the first track on American heavy metal band Ratt's album "Out of the Cellar".
 It was also featured on the soundtrack for the 1985 film "Weird Science".
 The song was composed by Robbin Crosby, Stephen Pearcy, and Joey Cristofanilli (who was briefly filling in for full-time Ratt bassist Juan Croucier), and it was the second biggest hit on the album (note: "Back for more" did not qualify for a chart position since it was not an actual single release), reaching number 87 on the "Billboard" Hot 100 and 38 on the "Billboard" Mainstream Rock Tracks chart.
Charles Sumner Woolworth (August 1, 1856 – January 7, 1947), was an American entrepreneur who went by the nickname of "Sum", opened and managed the world's first five-and-dime store in Scranton, Pennsylvania, and was founder of the "C. S. Woolworth & Co" chain of 5¢ & 10¢ stores.
 Sum's brother, Frank Winfield Woolworth was first to venture into the retail business with his own store, and soon after, he asked Sum to join him.
 Frank founded "F. W. Woolworth & Co", which later merged with other Woolworth affiliate stores to be the F. W. Woolworth Company.
 After the death of his brother, Sum became the longest serving Chairman of the F. W. Woolworth Company.
 During the early years, Sum also partnered with a long-time friend, Fred Kirby, to open a "Woolworth and Kirby" store in Wilkes Barre, Pennsylvania.
 When Fred bought out Sum's share, that store grew to become a "friendly rival" affiliate store, in close alliance with the two Woolworth brothers.
