Editorial
The May 1926 number of THE MATHEMATICS TEACHER was issued in honor of Professor David Eugene Smith, who in February of that year retired from active service at Teachers College, Columbia University. At that time his students and colleagues presented a portrait of Professor Smith to the college and gave a dinner in his honor. They endeavored to express to him their appreciation of the uniqueness of his work and their regard for him as a teacher and friend. Professor Smith's influence on the teaching of mathematics had been such that it seemed appropriate then to the editors of THE MATHEMATICS TEACHER to bring together in one number of the magazine the interpretations of his work and contributions as they were made on these occasions.
