Biography

Abt was born on 16 July 1850 in Bünzen. In 1882, while working in Paris, he designed and patented his rack-railway system that enabled at least one tooth of the rack to be permanently engaged. It was first used at the Rübeland Railway in the Harz mountains (Germany).[1]

Abt also developed the self-regulating "Abt Switch" for funicular railways[2] and led the construction of 72 mountain railways worldwide including the Visp-Zermatt, Gornergrat, Furka Oberalp and Ferrovia Monte Generoso railways. The most famous railway built with the Abt system is the Arica–La Paz railway in Bolivia.[1]

In 1903, as president of the Gotthardbahn company, Abt led buy-back negotiations with the German Confederation during the nationalisation of private railway companies. He received many honours, including an honorary doctorate (Doctor honoris causa) from the Technical University of Hannover and the John Scott Medal in 1889. He was also a patron and connoisseur of the arts, a member of the Swiss Federal Art Commission from 1904-1907 and the President of the Swiss Art Association from 1905-1911.

Pastimes

Abt was a keen collector of hammered gold artwork; he would not let go of any coin or medal whose special beauty aroused his artistic interest. His coin and art collection was auctioned off after his death.[1]

gollark: I wonder if anyone's tested newer TLC/QLC ones to death.
gollark: `smartctl` says `241 Total_LBAs_Written 0x0032 099 099 000 Old_age Always - 19835005814` but I have no idea what an "LBA" is.
gollark: I've got an 850 Evo sitting around from 2016 or so still in use, how can I check how much I have writted to it?
gollark: They can go *waaaaaay* beyond that, though.
gollark: Terabytes written.
