Ogen Melons were popularized commercially in Israel on the Kibbutz Ha’Ogen (meaning “The anchor”, founded 1947.)
They are named after that kibbutz.
The melons were not actually developed there; they were grown from seed brought from Israel to Hungary.  
The kibbutz’s own published timeline of important events does not mention Ha’Ogen melons specifically, though it does refer to melons:
“1956 – Summer – The first batch of Ha’Ogen’s Honey Melons (400 kg) is shipped abroad.” 
 “…introduced from Hungary a green-fleshed, smooth-skinned, sutured cultivar which they too named after their home community. However, the Ha’Ogen settlement is located on the sandy soils of the coastal plain that are unsuitable for dryland farming, and thus, irrigation is essential for the growing of crops there.” — Karchi, Z.

 “In Hungary, what you call Ha’ogen is sarga dinnye,” says Amaryll Schwertner, chef-owner of Boulette’s Larder, in the Ferry Building.” — Patterson, Daniel. Sphere of influence: An ambivalent melon eater falls hard for the Ha’ogen. San Francisco Magazine. September 2009.
