The year 1829 in science and technology involved some significant events, listed below.

Chemistry

• Isaac Holden produces a form of friction match.

Mathematics

• Peter Gustav Lejeune Dirichlet publishes a memoir giving the Dirichlet conditions, showing for which functions the convergence of the Fourier series holds; introducing Dirichlet's test for the convergence of series; the Dirichlet function as an example that not any function is integrable; and, in the proof of the theorem for the Fourier series, the Dirichlet kernel and Dirichlet integral. ^[1] He also introduces a general modern concept for a function. ^[2]
• Nikolai Ivanovich Lobachevsky publishes his work on hyperbolic non-Euclidean geometry. ^[3]
• S. D. Poisson publishes Sur l'attraction des sphéroides.

Medicine

• Dr Benjamin Guy Babington makes the first known use of a laryngoscope. ^[4]

Palaeontology

• Jules Desnoyers names the Quaternary period.
• Engis 2, part of the skull of a young child and other bones, recognised in 1936 as the first known Neanderthal fossil, is found in the Awirs cave near Engis in the United Kingdom of the Netherlands (modern-day Belgium) by Philippe-Charles Schmerling. ^[5]

Technology

• May – Cyrill Demian patents a version of the accordion in Vienna.
• June 30 – Henry Robinson Palmer files a British patent application for corrugated iron for use in buildings. ^[6]
• July 23 – In the United States, William Burt obtains the first patent for a form of typewriter, the typographer . ^[7]
• October 6–14 – The Rainhill Trials, a steam locomotive competition, are run in England and won by Stephenson's Rocket.
• December 19 – Charles Wheatstone patents the concertina in Britain. ^[8]
• William Mann invents the compound air compressor.
• Louis Braille publishes the first description of his method of embossed printing that allows the visually impaired to read. ^[9]

Higher Education

• Chalmers University of Technology founded in Gothenburg, Sweden.
• Technical University of Denmark (originally named 'College of Advanced Technology') founded in Copenhagen, Denmark.
• University of Stuttgart founded in Stuttgart, Germany.
• Ecole Centrale Paris (originally named 'École Centrale des Arts et Manufactures') founded in Paris, France.
