Engineers in the context of "Gerontechnology"

The Canal of the Pharaohs, also called the Ancient Suez Canal or Necho's Canal or Darius Canal, is the forerunner of the Suez Canal, constructed in ancient times and kept in use, with intermissions, until being closed in 767 AD for strategic reasons during a rebellion. It followed a different course from its modern counterpart, by linking the Nile to the Red Sea via the Wadi Tumilat. Work began under the pharaohs. According to Darius the Great's Suez Inscriptions and Herodotus, the first opening of the canal was under Persian king Darius the Great, but later ancient authors like Aristotle, Strabo, and Pliny the Elder claim that he failed to complete the work. Another possibility is that it was finished in the Ptolemaic period under Ptolemy II, when engineers solved the problem of overcoming the difference in height through canal locks.

The National Inventors Hall of Fame (NIHF) is an American not-for-profit organization, founded in 1973, which recognizes individual engineers and inventors who hold a US patent of significant technology. Besides the Hall of Fame, it also operates a museum in Alexandria, Virginia, sponsors educational programs, and a collegiate competition.

As of 2025, 652inventors have been inducted, mostly constituting historic persons from the past three centuries, but also including living inductees. Nominees must hold a US patent of significant contribution to the US welfare, and which advances science and useful arts.

A discens (Latin: discens, -entis) was a soldier of the military of ancient Rome who was in training to become an immunis, or specialist within the army.

Immunes took up the trades and skills of engineers, field medics, carpenters, and craftsmen. However, they were also fully trained and would be expected to fight in the infantry or cavalry if necessary. The discentes were probably exempted, like the immunes, from standard combat and camp duties since their main occupation would have been time-consuming technical training.
