Answer 1

1. Stone tools were humanity’s earliest technology, invented more than 2 million years ago by Homo habilis, an early human ancestor.
2. The first successful photograph, the daguerreotype, was invented by Louis-Jacques-Mandé Daguerre and Nicéphore Niépce in the 1830s.
3. The first saxophone was patented by Antoine-Joseph Sax in Paris in 1846. It was the first instrument to combine a reed (as in a clarinet) with a brass bell (as in a trumpet). Without its unique sound, we would never have heard jazz, or any of the music styles that followed in its footsteps.
4. The Bessemer process made it possible to mass-produce steel. This was a huge innovation in construction and led to many important advances.
5. Celluloid, the first synthetic plastic, is hugely important to life as we know it. It was developed in the 1860s and 1870s by industrialist and inventor John Wesley Hyatt.
