Baird worked as an instructor in psychology at
Johns Hopkins University, under the direction of the child psychologist and evolutionist
James Mark Baldwin from 1904 to 1906. He was then hired to a position at the
University of Illinois which, after a year, became an assistant professorship. The Illinois psychology department was headed by an educational psychologist,
Stephen S. Colvin. It was here that Baird's research interests began to spread from the "pure" experimental psychology that was advocated by Titchener into areas of applied psychology (Baird, 1906, 1908). In 1909, Baird was called to direct the storied psychology laboratory at
Clark University. Clark's president, the prominent psychologist
G. Stanley Hall, wanted Baird to replace Hall's long-time ally,
Edmund C. Sanford, who was being promoted to the presidency of the new undergraduate college at Clark. Baird had just become a cooperating editor of the newly founded
Journal of Educational Psychology, and Hall put him to work as executive editor of his own
American Journal of Psychology. Baird spent much of 1912 touring the psychology laboratories of Germany, France, Switzerland, and England in order to bring the latest developments back to the Clark laboratory. He also translated
Ernst Meumann's
Psychology of Learning (Meumann, 1913). Baird underwent surgery in 1913 to correct a urinary tract condition, which forced him to spend several months in hospital. In 1914, Baird married Barbara Morrison Sparks, the daughter of a physician in
St. Marys, Ontario. In 1916 Baird was elected to membership in the venerable
American Academy of Arts and Sciences. The duties of being laboratory director prevented Baird from conducting much original research during this period, but he was able to co-edit and contribute a chapter on perfect pitch to a
Festschrift celebrating Titchener's 25th year at Cornell (Baird, 1917a). He also contributed a chapter (Baird, 1917b) to another
Festschrift in honor of the retirement of Cornell philosophy professor
James Edwin Creighton, who had been the founding president of the
American Philosophical Association (and was a fellow Canadian). Also in 1917, Hall, Baird, and another Clark professor named
Ludwig R. Geissler collectively founded a new periodical, the
Journal of Applied Psychology. Baird published an article based on research he had conducted into the optimal type-font to be used in telephone books in the first volume (Baird, 1917c). Around 1917 Baird became aware that Hall was grooming him to succeed both Hall and Sanford as president of a newly unified Clark College and Clark University upon their joint retirement in 1920. In 1918, during World War I, Baird was elected president of the
American Psychological Association. During his term he was called to
Washington D.C. to serve as Vice-Chair of the
National Research Council's Psychological Committee, a position in which he developed a program for the assessment and rehabilitation of injured soldiers returning from the war. ==Illness and death==
