The development of the mathematical department of the Educational Times from 1847 to 1862.

Mathematics held an important place in the first twelve of years of the Educational Times (1847-1923), and in November 1848 a department of mathematical questions and solutions was launched. In 1864 this department was reprinted in a daughter journal: Mathematical Questions with Their solutions from The Educational Times (MQ). This thesis concentrates on the development of this department from its
inception until 1862, when William John Clarke Miller became its editor; and is considered in terms of the editors, contributors and mathematics. To facilitate this
research, a source-oriented database using K L E I O (kleio) software was constructed. It contains data taken from the questions and solutions and also miscellaneous items from the journal. Database analysis was used in conjunction with traditional, archival sources; for example, the respective, previously unknown correspondence of two of the main contributors, Thomas Turner Wilkinson and Miller.
The development of the department fell into two main periods: the early 1850s when it was edited by Richard Wilson then James Wharton and had an educational bias; and
the late 1850s when it was dominated by Miller and Stephen Watson who contributed moderately complex problems of a reasonably high standard on conic sections, probability and number theory.
In 1850 Miller started contributing with a group of pupils and masters, including Robert Harley, from the Dissenters' College, Taunton. Another group of contributors which emerged was one of northern geometers, with whom Wilkinson was connected. He collaborated with Thomas Stephens Davies on geometry and this influenced his contributions to the department.
Miller edited the department from 1862 to 1897 and MQ from 1863 to 1897 and made MO an international journal of renown for its original research. It contained contributions from some of the most eminent national and international
mathematicians, including Cayley, Sylvester, Hirst and Clifford. The start of this new phase is briefly introduced and reviewed.
