The remainder of the first of the two Cathar wars now essentially focused on Simon's attempt to hold on to his fabulous gains through winters where he was faced, with only a small force of confederates operating from the main winter camp at Fanjeau, with the desertion of local lords who had sworn fealty to him out of necessity — and attempts to enlarge his newfound domains in the summer when his forces were greatly augmented by reinforcements from northern France, Germany and elsewhere.

In graph theory, much research was motivated by attempts to prove the four color theorem, first stated in 1852, but not proved until 1976 ( by Kenneth Appel and Wolfgang Haken, using substantial computer assistance ).

In it, Husserl for the first time attempts a historical overview of the development of Western philosophy and science, emphasizing the challenges presented by their increasingly ( one-sidedly ) empirical and naturalistic orientation.

A quote from the Principia Discordia, the first holy book of Discordianism, attempts to clear this up:

In addition, he was the first to isolate the chemical urea from urine.

In an effort to isolate Germany, France went to great pains to woo Russia and the United Kingdom to its side, first by means of the Franco-Russian Alliance of 1894, then the 1904 Entente Cordiale with the U. K, and finally the Anglo-Russian Entente in 1907 which became the Triple Entente and eventually led Russia and the UK to enter World War I as Allies.

Johan Gottlieb Gahn was the first to isolate an impure sample of manganese metal in 1774, by reducing the dioxide with carbon.

The first is that many of the gas piston modifications for the M4 isolate the piston so that piston jams or related malfunction require the entire weapon be disassembled, such disassembly cannot be performed by the end user and requires a qualified armorer to perform out of field, whereas any malfunction with the direct-impingement system can be fixed by the end user in field.

During his search for argon, Ramsay also managed to isolate helium for the first time while heating cleveite, a mineral.

Eugène-Melchior Péligot was the first person to isolate the metal and its radioactive properties were discovered in 1896 by Antoine Becquerel.

* Jay Levy, who, along with Robert Gallo at the National Cancer Institute and Luc Montagnier at the Pasteur Institute, was among the first to identify and isolate HIV as the causative agent in AIDS

He later postulated the existence of other essential nutrients, which became known as B < sub > 1 </ sub >, B < sub > 2 </ sub >, C, and D. In 1936 he determined the molecular structure of thiamin, though he was not the first to isolate it.

He was the first to isolate nicotinic acid ( also called niacin or vitamin B < sub > 3 </ sub >).
