author
A lively early-20th-century popular science writer, he turned big subjects like mathematics, invention, electricity, and model aviation into practical reading for curious general audiences.

by V. E. (Valentine Edward) Johnson
Valentine Edward Johnson was a British author best known for clear, accessible nonfiction that explained science and technology to everyday readers. His books include The Theory and Practice of Model Aeroplaning, Modern Inventions, Electrical Recreation, and The Uses and Triumphs of Mathematics, showing a wide interest in how new ideas worked in real life.
His writing appeared during a period of rapid change in engineering and transport, and he seems to have had a gift for making technical topics feel approachable rather than intimidating. That combination makes his work a good fit for readers who enjoy classic popular science and hands-on explanations.
Available library records and author listings confirm his published works, and a Wikisource author page notes that he died in 1946. I wasn't able to confirm further biographical details such as his birthplace or career outside writing from the sources I found, so this overview focuses on the parts of his life and work that were clearly supported.
