【Author】Yan Leopoldovich Lary (1900-1977)**
A distinguished children's author, science fiction writer, and biologist. He has worked in various occupations throughout his life, from a waiter to a fish factory manager, participated in World War I and the Civil War, and witnessed the October Revolution. As a science fiction writer, he made his debut with the novella "Windows to the Future" and later wrote the utopian novel "The Land of Happiness," depicting a communist future. The critics issued devastating reviews, and Lary's works were no longer published, and his novels were withdrawn from libraries. It took a long time for his works to return to the readers' view. His early science fiction works did not bring the author great fame, but he left an immortal name in the history of children's literature with his outstanding children's book "Journey into the World of Insects" (also known as "The Extraordinary Adventures of Karik and Valka").
