Ida Freund (1863–1914) was a chemist and educationalist who is most commonly remembered as the first female chemistry lecturer in the United Kingdom. Originally published in 1920, this book consists of a series of illustrative experiments, derived from the material collected in Freund's notebooks and students' records during her time at Newnham College, Cambridge. Out of an intended twenty chapters, ten were completed at the time of her death in May 1914. These chapters were left almost ready for press and only minor editorial changes were made prior to publication. This book will be of value to anyone with an interest in Freund, chemistry and the history of science.
