Los Angeles: Times-Mirror Press, 1923-25. Infomercial, in the guise of a biography of Milton Berry, a one-time shoeshine boy whose California polio clinic gained widespread fame in the Twenties and Thirties for restoring movement to victims of infantile paralysis who had previously been declared beyond rehabilitation. Berry's methods were widely attacked by mainstream orthopedists, but he claimed a remarkable record of success with his patented technique of "Patho-Kinesiology," which involved manual manipulation of affected limbs but nor surgery or prescription medication. Originally published as a series of articles in the Los Angeles Times. The second edition adds a section of first-hand testimonials and an expanded preface. The first edition somewhat scarce. First edition (1923) together with the greatly revised and expanded second edition (1925). Two octavo volumes, uniformly bound in black cloth blocked in red; 96+157pp. Mild external wear but generally clean and unmarked; both volumes Near Fine. Identical portrait frontispiece to both editions.
