Within a few years Louis Pascal Casella joined Cesare in a partnership and the new Casella name was born. In the early years the product ranges being exported around the world included exploration, navigation, photographic, meteorological and medical research instruments. Our early customers included Charles Darwin and Dr. Livingstone who used many of the early Casella products on their travels of discovery. During the 19th century, the product range continued to grow and Casella exhibited instruments including theodolites and surveying equipment at the first ’’Great Exhibition’’ held in the Crystal Palace, Hyde Park London in 1851.
