cember 1949 issue of ANALYTICAL CHEMISTRY, one finds 36 research ar ticles, 15 "Notes on analytical proce dures", and one lengthy report on rec ommended specifications of microchemical apparatus. Of the 36 full ar ticles, the vast majority involved in strumental methods, but only a half dozen or so could be stated to involve a fundamental study. The decade of the 1940's witnessed the establishment of several other an alytical journals in the immediate postwar era of 1946-7. These included the broad-based journals Analytica Chimica Acta and Zhur. Anal. Khim., as well as the specialized journals Ap plied Spectroscopy and Spectrochimica Acta. After the backlog of wartime research had been assimilated, publi cations remained in a stable configu^ ration for the remainder of the decade, to undergo proliferation and expan sion again as research generally moved into its long-term growth pattern. Textbooks were slower than jour nals to respond to postwar changes. Although a book by W. N. Lacey had appeared under the title "Instrumen tal Methods of Analysis" as early as 1924, the teaching of comprehensive undergraduate and graduate courses involving spectrochemical, electro chemical, and other instrumental methods did not become common place until after the appearance of the pioneering text of the same title by Willard, Merritt, and Dean in 1948. This text was closely tied to commer cial instruments, and only briefly cov ered fundamental principles, but it greatly influenced the modernization of undergraduate curricula. During the late 1940's, ANALYTI CAL CHEMISTRY took an active part in the professional activities of the ACS Division of Analytical Chemistry and took editorial positions on mat ters of professional interest generally. In an editorial in March 1947 entitled "The Profession of Analytical Chem ist", several recommendations were made including "insistence upon a sharp distinct line of demarcation in title between the professional chemist and the laboratory technician", the development of "ideal curricula" in analytical chemistry at the undergrad uate and graduate levels, including the field of instrumentation, "the estab lishment of at least one award for out standing work in the field of analytical chemistry. In addition, several awards for postgraduate students are highly desirable", and "consideration of ways and means of educating industry and

particularly top-flight management on the true importance of analytical chemistry and analytical chemists". In June 1947 excerpts were pub lished of several letters in response to this editorial. These letters, although not identified as to source, represent an interesting cross section of atti tudes among industrial and academic analytical chemists of that time. In October 1947 the establishment of the Fisher Award in Analytical Chemistry was announced and traced directly to the March editorial. In November and December 1947 and January 1948, there appeared a series of short arti cles written by industrial and academ ic chemists under the general title, "What Is Analysis? What Is the Role of the Analyst?" In January 1948 under the title "Of ficial at Last", the formal adoption of the name ANALYTICAL CHEMISTRY, which had been in informal use for the previous year, was announced. In April 1948 another editorial urged industrial sponsorship of post graduate fellowships and endowed chairs of analytical chemistry. In May 1948 the first Summer Symposium on Analytical Chemistry was announced under the topic "Nucleonics and Ana lytical Chemistry". This series, cosponsored by the Division and the JOURNAL, continues to this day. In October 1948, again as a direct result of the March 1947 editorial, the Merck Fellowship in Analytical Chem istry was announced. This nationally competitive fellowship was continued for 9 years, 1949-57 inclusive, and formed the pattern for the Division fellowships that were established in 1966. In April 1949 in an editorial entitled "The Scope of Analytical Chemistry", a special plea was made for authors to submit fundamental articles. The worldwide scope of its coverage was also emphasized. As the decade drew to a close, a gradual expansion of PhD-granting programs in analytical chemistry, a new awareness of fundamental re search in this field as opposed to the empirical development or improve ment of analytical methods, and the emergence of research in instrumenta tion as opposed to instrumental analy sis, especially in industry, were taking place. All of these trends were to con tinue and accelerate later, but the be ginnings were already evident in the late 1940's. Other articles in this sym posium will cover developments in subsequent decades.
