Rudolf Halin (February 3, 1934, Uerdingen – November 14, 2014, Mölln)[1] was a German graph theorist, known for defining the ends of infinite graphs,{{sfnp|Halin|1964}} for Halin's grid theorem,{{sfnp|Halin|1965}}[2] for extending Menger's theorem to infinite graphs,{{sfnp|Halin|1974}} and for his early research on treewidth and tree decomposition.{{sfnp|Halin|1976}} He is also the namesake of Halin graphs, a class of planar graphs constructed from trees by adding a cycle through the leaves of the given tree; earlier researchers had studied the subclass of cubic Halin graphs but Halin was the first to study this class of graphs in full generality.{{sfnp|Halin|1971}} Halin earned his doctorate from the University of Cologne in 1962, under the supervision of Klaus Wagner and Karl Dörge, after which he joined the faculty of the University of Hamburg.[3] In February 1994, a colloquium was held at the University of Hamburg in honor of Halin's 60th birthday.[4] Selected publicationsResearch papers
