See also lojbau, loglo. The Loglan language, predecessor of Lojban. The first 'logical language', Loglan was conceived and largely developed by Dr. James Cooke Brown, an American professor of sociology, during the mid- to late 20th century, starting in 1955. Loglan gained notoriety in a 1960 Scientific American article, but was not fleshed out until years afterward. A dispute over rights to the language (eventually resolved in court) led to the creation of Lojban in 1987. Extensive documentation on Loglan can be found (as of June 2018) at loglan.org.
