Context: Hubert Léonard (7 April 1819 – 6 May 1890) was a famous Belgian violinist, born at Liège.  His earliest preparatory training was given by a prominent teacher of the time, August Rouma, after which he entered the Paris Conservatoire in 1836.  There he studied for three years under François Antoine Habeneck.  In 1844 he started his extended tours which established his reputation as one of the greatest of virtuosos. From 1848 to 1867 he held the position of principal professor of violin playing at the Brussels Conservatoire, having succeeded the celebrated Charles de Bériot.  Owing to ill health, he resigned and settled in Paris, where he spent the rest of his life, and where he gave lessons.  Among his notable students were Alfred De Sève, Martin Pierre Marsick, Henri Marteau, Henry Schradieck, and César Thomson.  He wrote a significant pedagogical work entitled "Ecole Léonard".

He is married to the Swedish artist Susann Wallander.  Peter de Ru is represented at several state institutions like the Swedish Radio, the Nobel Museum, the Karolinska Hospital, and since 2011 at the National Museum in Stockholm (the Swedish State portrait gallery at Gripsholm). Peter de Sève is an American artist who has worked in the illustration and animation fields.  He has drawn many covers for the magazine "The New Yorker".  As a character designer, he worked on the characters of "A Bug's Life", "Finding Nemo", "Robots", the four "Ice Age" films (including Scrat), and on the main animal character E.B. (voiced by Russell Brand) in the 2011 Easter themed comedy film "Hop".  Most recently, he designed the characters for "Arthur Christmas", for which he was nominated for Annie Award.

Alfred De Sève (May or June 1858 – 25 November 1927) was a Canadian violinist, composer, and music educator.

Fyre, formerly de Jong Explorer, is a cross-platform tool for producing artwork based on histograms of iterated chaotic functions.  It implements the Peter de Jong map in a fixed function pipeline through either a GTK GUI frontend, or a command line facility for easier rendering of high-resolution, high quality images.  The program was renamed from de Jong Explorer to Fyre simply because "<nowiki>'It wasn't taken yet'</nowiki>" and so that in the future, it could support more functions than just the standard Peter de Jong map.  Fyre features a sidebar on the left to which the user can input the required variables and on the right is displayed the result of the equation.
