This document is an Edison notebook from 1909. At the beginning of the book is a memorandum from William H. Meadowcroft to Edison, dated June 28, 1909, indicating that a copy has been made of the handwritten notes in this book. Four brief critiques by Edison of the biography in progress appear on the following page, while subsequent pages narrate incidents in his life. Most of the entries pertain to Edison's work on electric lighting and power and provide an account of his former employee, Sigmund Bergmann. Two memoranda from Edison to Meadowcroft appear on page 22. Notations by archivist Norman R. Speiden can be found on the inside front cover and on page 28. The book contains 32 numbered pages; an erasure on the 33rd page obscures one additional sentence by Edison.
