Chemistry throughout the centuries Examining the development of science and technology over the centuries gives us insight into their impact on communities, the environment, and global resources. Joseph Wright of Derby was an influential painter of the late 18th century. This painting entitled The Alchemist: in Search of the Philosopher’s Stone depicts a moment in time that forms a part of the history of chemistry. This painting of Louis Pasteur in 1885 by Albert Edelfelt is in the Musée d’Orsay in Paris, France. It depicts Pasteur, a French biologist, microbiologist and chemist at work in his laboratory. Chemistry and technology work hand in hand in the modern laboratory. Discuss how these images portray the journey through time from alchemy to modern scientific research in the field of chemistry.

Students may mention the following points in their response: The change in appearance of the laboratories over time; The clothes worn by the scientists in the different images; The lack of electricity in the images when compared to a modern laboratory; The agenda of the early scientists compared to the modern scientific community.
