Dr. Immanuel Velikovsky was one of the greatest scientists of modern times. However, because of his extraordinary findings in many different disciplines, he fell victim to one of the worst slandering campaigns since the Middle Ages.This book is a supplement to Velikovsky's biography "ABA - The Glory and the Torment", written by his daughter Ruth. Here, she publishes original letters in their entirety, shedding a revealing light on the defamatory campaign Velikovsky and his scientific work have been subjected to by the scientific establishment down to the present day. In a second part, plasma physicist C.J. Ransom undertakes a reevaluation of Velikovsky's research from the point of view of recent scientific developments.
