This signed volume of The Evolution of Physics: The Growth of Ideas from Early Concepts to Relativity and Quanta, written by Albert Einstein and Leopold Infeld, was published by Simon & Schuster, New York. The title page is dated 1954 and bears a prominent handwritten signature of Albert Einstein beneath the publication information.

First published in 1938, The Evolution of Physics occupies a distinctive place among Einstein's writings. Conceived for the general reader, the book traces the transformation of physical thought from classical mechanics through field theory and ultimately to relativity and quantum physics. Rather than a later biography or commentary on Einstein, it is a work in which Einstein himself participated in presenting the intellectual development of modern physics, giving a signed copy an especially compelling association between author, autograph, and subject.

Einstein's signature is attractively positioned in the lower portion of the title page, directly beneath the printed names of Einstein and Infeld. Executed in dark ink, it displays a fluid horizontal movement, closely connected letter forms, compressed internal structure, and the distinctive progression of the "Einstein" portion associated with his mature autograph. Its placement leaves the typography unobstructed while making the autograph immediately visible when the volume is opened.

The book retains its striking blue period dust jacket, prominently displaying the title, subtitle, and the names of Einstein and Infeld. The jacket shows expected age-related rubbing, edge wear, creasing, and small losses, while retaining the strong graphic character of its mid-century design.

Combining Albert Einstein's autograph with one of his own major works on the development of modern physics, the present volume has exceptional thematic resonance. It represents an appealing intersection of scientific history, twentieth-century intellectual history, and autograph collecting, with particular interest for collectors seeking an Einstein signature preserved directly within a work bearing his authorship.
