In the late 1950s, Langsner and Peter Selz, then professor at the Claremont Colleges, observed a common link among the recent work of John McLaughlin (1898–1976), Lorser Feitelson (1898-1978), Karl Benjamin (1925-2012), Frederick Hammersley (1919–2009) and Feitelson's wife Helen Lundeberg (1908-1999).
В конце 1950-х Лангснер и Peter Selz, в дальнейшем профессор Claremont Colleges, заметили общие черты в работах Джона Дуайра Маклафлина, Lorser Feitelson, Karl Benjamin, Frederick Hammersley и Helen Lundeberg.
