of chemistry at KTH, took over. He led a full reorganisation of the institute in 1846–1848, after which he returned to his post in Falun. An entrance test and a minimum age of 16 for students was introduced, which led to creating proper engineering training at the institute. In 1851, the engineering program was extended from two years to three. In the late 1850s, the institute entered a time of expansion. In 1863, it received its own purpose-built buildings on Drottninggatan. In 1867, its regulations were again overhauled, to state explicitly that the institute should provide scientific training to its students. In 1869, the School of Mining in Falun was moved to Stockholm and merged with the institute. In 1871, the institute took over the civil engineering course formerly arranged by the Higher Artillery College in Marieberg. In 1877, the name was changed into the current one, which changed KTH's status from Institute (institut) to College (högskola), and some courses were extended from three years to four. Architecture was also added to the curriculum. In 1915, the degree titles conferred by KTH received legal protection. In the late 19th century, it had become common to use the title civilingenjör (literally "civil engineer") for most KTH-trained engineers, and not just those who studied building and construction-related subjects. The only exception was the mining engineers, which called themselves bergsingenjör ("mountain engineer"). For a while, the title civilingenjör was equal to "KTH graduate" but in 1937, Chalmers in Gothenburg became the second Swedish engineering college which were allowed to confirm these titles. In 1917, the first buildings of KTH's new campus on Valhallavägen were completed, and still constitute its main campus. Although the engineering education of the late 19th and early 20th century were scientifically founded, up until the early 20th century, research as such was not seen as a central activity of an Institute of Technology. Those engineering graduates which went on to academic research had to earn their doctorates, typically in physics or chemistry, at a regular university. In 1927, KTH was finally granted the right to confer its own doctorates, under the designation Teknologie doktor (Doctor of Technology), and the first five doctors were created in 1929. In 1984, the civilingenjör programs at all Swedish universities were extended from four years to 4.5. From 1989, the shorter programs in technology arranged by the municipal polytechnical schools in Sweden was gradually
