Louis) is an American physicist and professor at Brandeis University.Meyer graduated from Harvard University in 1965 with a bachelor's degree and in 1970 with a doctoral degree with advisor David Turnbull and dissertation on effects of electromagnetic fields on the structure of liquid crystals.
At Harvard, Meyer was a post-doctoral student and became in 1971 an assistant professor and in 1974 an associate professor.
Recently, his research has concentrated on liquid crystalline gels and elastomers, and textures and modulated phases in ferroelectric liquid crystals.
In 2006 Meyer received, jointly with Noel A.
Clark, the Oliver E.
Buckley Condensed Matter Prize for basic theoretical and experimental studies of liquid crystals, in particular their ferroelectric and chiral properties (laudation).
He was elected in 1985 a Fellow of the American Physical Society and received the 2004 Benjamin Franklin Medal of the Franklin Institute.
