Eichleiter had eight siblings of whom three died in an early age and after his mother's death his father had to take care of them.

After finishing his studies he worked first as a locksmith then as a technical drawer in Erfurt, Thuringia at the main workshop of the Thüringer Bahn.

In 1854 he was employed by the Cramer-Klett (predecessor of MAN SE) where he was commissioned to hand over the produced wagons to the 'Tisza Railway' (Tiszai Vasút) company in Szolnok, Austria-Hungary.

[1] Before his death Ganz concluded with Eichleiter, Ulrich Keller and Mechwart a secret, final agreement that stated, in the case of his unexpected death Eichleiter has to become the head of the company, Eichleiter gets 22% of the shares, Keller gets 10% and Mechwart 8% and his heirs living in Switzerland get the majority (the other 60%) of the shares and they cannot sell the company to outsiders for ten years.

But after two years the heirs of Ganz sold the company to Eichleiter, Keller and Mechwart.

[4] Eichleiter was a board member of the 'Pest-Buda Beauty Committee' (Pest-Buda Szépészeti Bizottság) which served as an architectural judging association.

He was also a member of the economic council of the Budapest-based 'First Hungarian Wagon Factory Inc.'(Első Magyar Vasútikocsigyár Rt.

),[5] a technical advisor in a cornstarch-producing company and in the Salgótarján, Austria-Hungary based 'Salgótarján Coal Mine Ltd.' (Salgótarjáni Szénbányamű).

So he decided to change his way of life and move to Rorschach am Bodensee, Canton of St. Gallen, Switzerland where he bought the 'Weinhalde Villa'.

He supported a lot of charity project in Rorschach: theatre, gymnastics association, well drilling for the public etc.

However, in other developed countries that kind of law already existed at that time and therefore the Swiss intellectual treasure was easier to get stolen.

After all their children left family nest, Eichleiter sold his house and moved to Munich, Bavaria.
