Gisi died at the age of 17 on July 16, 1934, in while mountaineering in Houches, Haute Savoie (France).

Gisi went on a trip to the French Alps with friends, but had a dispute with his friends on the train and decided to go on his own. He disappeared and was never seen again. It is believed that he fell in a crevasse.

His father Moritz came down from Paris and looked for him in the mountain with a search dog, but in vain.

Post Mortem

In 1937, Gisi's mother Ronya set up a scholarship in memory of her son to send a young pioneer from Palestine on a ten day skiing trip to Lebanon. The recipient, Karl Welisch from Kibbutz Ein Gev, sent her a letter in the spring of 1938 to thank her and describe his trip. He mentions that he hopes the recipient of next year's scholarship will enjoy it as much as he did, but there is no information whether this scholarship existed for more than a year.

I hope that my successor, the recipient of the Gisi Abraham Scholarship for 1938, will have an equally beautiful experience and thus a number of young people will remember with gratitude that the Gizy Abraham Scholarship allows them to ski.

For the 10 beautiful days on which I will always remember me, my deepest thanks.

Of interest is the following excerpt:

The population, Christian Maronites, are friendly, cheerful people who have welcomed us with open arms. (...) The foundation of the ski hut you have envisaged, would be of great importance for the development of skiing in Lebanon (... and) would reinforce the ties between Palestine and the Lebanon.

In 1938, the writer Jacques Vichniac, better known under his pen name Jacques Givet, published a book of poems written between the age of 17 and 20, "Nous N'irons Plus au Bois". The collection included a poem dedicated to Gisi:

A la memoire de G. A.

(...) Mets un bandeau sur la tête
il est temps de dresser des camps de détresse
sur les glaciers et de rendre a la terre
ce qu'a la terre tu as volé (...)

He autographed a copy of his book to "Madame Abraham" in 1940. (The date is unclear: 12+1-4 .40

Born in 1917, the same year as Gisi, I assume Jacques Vichniac/Givet and Gisi were classmates.
