The Puskás family from Ditró[8] (today Harghita County of Romania), was part of the Transylvanian Hungarian nobility.

[citation needed] Puskás was working on his idea for a telegraph exchange when Alexander Graham Bell invented the telephone.

In 1879 Puskás set up a telephone exchange in Paris, where he looked after Thomas Edison's European affairs for the next four years.

In Paris he was greatly helped by his younger brother Ferenc Puskás (1848–1884), who later established the first telephone exchange in Pest.

According to a contemporary scientific journal, at most 50 people could listen to Edison's telephone at the same time, if one more person was connected, none of the subscribers could hear anything.

However, in 2008, the Hungarian National Bank issued a 1000 Forint commemorative coin in honor of Puskás and the 115th anniversary of the introduction of the Telefon Hírmondó.
