There?s often no better way of learning about a historical period than through the biographies of those who lived at the time. This applies equally to the history of science. This concise book traces the evolution of modern chemistry through the rich stories of those who devoted their lives to its advancement. It?s a valuable resource for Waldorf teachers who want to add colour and context to chemistry lessons, or to characterise the different phases of understanding that have led to our current sophisticated levels.
