In the 19th and early 20th centuries archaeological typologies continued to be constructed using a combination of empirical observation and intuition. According to Eggers,[13] most archaeologists give Oscar Montelius the credit for the first serious application of the typological method, but in Eggers' view, his contemporary colleague from Stockholm, Hans Hildebrand made important contributions to the development of the methodology as well. Hildebrand published a fundamental paper on the development of fibulae in the 1870s using the typological method, whereas Montelius at the same time went to international congresses and published smaller papers on this method.
