In the whole of Szeklerland, Ditrău is the only village, after which a combination of minerals and rocks was named (in 1866): this is the ditroit. The varied lithological structure during the Mesozoic era in the area of Ditrău has attracted the attention of geologists who have found an interesting rock compositions, characterizing it as being unique.
Ditrău is a large commune of 5,000 inhabitants, located in the northeastern part of the Giurgeu Intra-Carpathian basin. The village is situated at an altitude of 742 m. Between the 18-19th century the core of the settlement, due to the rapid increase of the population, merged with other little settlements giving today's commune. In the eighteenth century other further away settlements such as Borsec, Bilbor,Tulgheş and Corbu belonged to Ditrău. However, in the nineteenth century these settlements willingly seceded from Ditrău.
Among the famous people born in Ditrău, we must mention Puskás Tivadar, the inventor of "The Telephone Herald" in Budapest. Although the locals from Ditrău consider him to be one of them, only his grandparents lived here. The family indeed stems from Transylvania, but he was born in Budapest. He studied in Vienna and while he was working for Edison he built the telephone exchange. The first experimental telephone exchange was based on the ideas of Puskás, and it was built by the Bell Telephone Company in Boston in 1877. In 1887 Puskás introduced the multiplex switchboard, that had an epochal significance in the further development of telephone exchange.
