Question

one major technological advances in the 19th century

Answer 1

The electric telegraph (developed and commercialized in the 1830s–1860s) is one major 19th‑century technological advance. Samuel Morse’s system (first public demonstration in 1844 with the message “What hath God wrought”) and parallel systems in Europe turned coded electrical pulses sent over wires into instant long‑distance communication. Combined with the later laying of submarine cables (notably the successful transatlantic cable in 1866), the telegraph collapsed communication time from days or weeks to minutes.

Impact: it transformed commerce, journalism, finance and military command by enabling rapid coordination and information flow across continents, and it laid the technical and organizational foundations for later electrical communications (telephone, radio, Internet).
