Question: What nationality was the Lax pair's namesake?
Context: Cribbage, sometimes called cribbage pocket billiards, cribbage pool, fifteen points and pair pool, is a two-player pocket billiards game that, like its namesake card game, has a scoring system which awards points for pairing groups of balls (rather than playing cards) that total 15.  Played on a standard pool table, participants who <dfn id="">pocket</dfn> a ball of a particular number are required to immediately pocket the companion ball that tallies to 15 when added to the prior ball's number.  The goal is to score 5 paired cribbages out of a possible 8, with the exception that the last ball, required to be the 15 ball, is not paired but alone counts as 1 cribbage. The 9th Street Expressway and the 12th Street Expressway are a pair of spurs connecting Interstate 395 (I-395; Southwest Freeway) with Downtown Washington, D.C..  The two carriageways are 0.2 mi apart from each other, and gain their namesake from the roads that they lead into once reaching the downtown Federal Triangle neighborhood. Starting in the 1890s, the Italian "Regia Marina" (Royal Navy) began building a series of modern battleships.  Early designs were marked by their small size, light armor, and high speed compared to contemporary foreign counterparts.  The first pre-dreadnought battleship design, the "Ammiraglio di Saint Bon" class , was constrained by budgetary limits imposed by the legislature.  Two ships were ordered by the class's namesake, Admiral Simone de Pacoret Saint Bon, though the design was also influenced by Benedetto Brin, who replaced di Saint Bon as naval minister after his death.  Brin designed the next pair of battleships, the "Regina Margherita" class .  These ships were larger than the preceding class, and were intended to challenge the Austro-Hungarian "Habsburg"-class battleship s then under construction.  Brin himself died during the construction process.  Vittorio Cuniberti designed the next class of small pre-dreadnoughts, the "Regina Elena" class , which were the fastest battleships in the world at the time of their completion.  These ships all served in the Italo-Turkish War of 1911–12, where they were primarily used to provide naval gunfire support for the Italian ground troops, as the Ottoman Navy largely confined itself to port. Colegio San Agustín – Makati (abbreviated as CSA or CSA-Makati) is a private, co-educational Catholic school conducted by the Order of Saint Augustine.  It is located on Palm Avenue, Dasmariñas Village, Makati City, Philippines.  While it is not the oldest Augustinian school in the Philippines named Colegio San Agustín (that distinction belongs to Colegio San Agustin-Bacolod), it is the most prominent and famous among its namesake.  The school is one of the most diverse in the Philippines in terms of nationality, with 11% of the student population coming from over 40 countries. Rainy Lake Falls is a waterfall on the inlet stream of namesake "Rainy Lake" in Chelan County, Washington.  The stream heads in a pair of small lakes and the remaining portions of the Lyall Glacier, and flows down a cascade that is said to be approximately 850 ft high. Leon N Cooper (born February 28, 1930) is an American physicist and Nobel Prize laureate, who with John Bardeen and John Robert Schrieffer, developed the BCS theory of superconductivity.  He is also the namesake of the Cooper pair and co-developer of the BCM theory of synaptic plasticity. Peter David Lax (born 1 May 1926) is a Hungarian-born American mathematician working in the areas of pure and applied mathematics.  He has made important contributions to integrable systems, fluid dynamics and shock waves, solitonic physics, hyperbolic conservation laws, and mathematical and scientific computing, among other fields.  Lax is listed as an ISI highly cited researcher. The Bears Ears are a pair of mesas located in San Juan County in the southeastern Utah, United States.  They are protected as part of and the namesake of the Bears Ears National Monument, managed by the Bureau of Land Management and United States Forest Service.  The Bears Ears are bordered on the west by Dark Canyon Wilderness and Beef Basin, on the east by Comb Ridge and on the north by Indian Creek and Canyonlands National Park.  Rising 2000 ft above Cedar Mesa to the south, the Bears Ears reach 8700 ft in elevation and are named for their resemblance to the ears of a bear emerging from the horizon. In mathematics, in the theory of integrable systems, a Lax pair is a pair of time-dependent matrices or operators that satisfy a corresponding differential equation, called the "Lax equation".  Lax pairs were introduced by Peter Lax to discuss solitons in continuous media.  The inverse scattering transform makes use of the Lax equations to solve such systems. Along the Templar Trail: Seven Million Steps for Peace is a non-fiction travelogue written by Brandon Wilson, published in 2008 by Pilgrim's Tales, Inc..  It is the true story about Wilson, an American, and "Émile", a 68-year-old Frenchman, who set off in the spring of 2006 from Dijon, France to hike the route Godfrey de Bouillon and his army traveled in 1096 to Jerusalem.  Traveling simply with backpacks and trusting in the kindness of strangers, the pair have two goals: to carry a message of peace along a route historically used for war, and to establish a pilgrimage path others might follow regardless of nationality, culture and religion.
