Bio/Historical Note: Lloyd Lyne Dines (1885-1964) was an American-Canadian mathematician, known for his pioneering work on linear inequalities. Dines received a BA in 1906 and an MA in 1907 from Northwestern University. Dines earned a PhD in 1911 from the University of Chicago under Gilbert Bliss with the thesis “The highest common factor of a system of polynomials in one variable, with an application to implicit functions.” In 1911 Dines became an instructor of mathematics at Columbia University and then became an associate professor at the University of Arizona. From 1915 to 1934 Dines was a professor at the University of Saskatchewan. In 1928 he was elected to the Royal Society of Canada. In 1932 Dines was an invited speaker at the International Congress of Mathematicians in Zürich. From 1934 to 1945 he was a professor at the Carnegie Institute of Technology and chair of the mathematics department. After his retirement in 1945, Dines held visiting professorships at the University of Saskatchewan, Smith College, and Northwestern University. Dines died in 1964 in Quincy, Illinois.
