<p>Stub for Raphael Finkel — point quadtree co-inventor</p> <p><b>New page</b></p><div>&#039;&#039;&#039;Raphael Finkel&#039;&#039;&#039; is a computer scientist known for his work in programming languages, compiler design, and data structures. With [[Jon Bentley]], he invented the [[point quadtree]] in 1974, a spatial data structure that generalizes the binary search tree to two dimensions. Finkel&#039;s contributions span the boundary between theoretical computer science and practical systems design, and his work on the point quadtree anticipated the later development of spatial indexing techniques used in modern geographic information systems and computer graphics.<br /> <br /> [[Category:Computer Science]]<br /> [[Category:People]]<br /> [[Category:Data Structures]]</div>
