Scope and Content of Series
Series 3) WRITINGS contains manuscript and printed materials created by Leo Szilard. Also included are materials created by
others, which can be found in the "Publications By Other Authors" subseries. Most materials in this series date from 1946
and after. Arranged into nine subseries: A) Writings by Leo Szilard, B) Patents, C) History, D) Interviews, E) Memoranda,
F) Speeches, G) Handwritten Notes, H) Notebooks I) Publications by Other Authors.
A) Writings by Leo Szilard: Essays, scientific papers, and literary works produced by Szilard, including the manuscript for
The Voice of the Dolphins. These materials are arranged alphabetically by title. Works with changing titles are brought together under the latest title.
Works that appear without title are segregated into "dated" and "non-dated" folders at the beginning of the subseries.
B) Patents: Documents and related materials in the form of drafts, figures and notes. These are organized chronologically.
Of special interest are the early patents in refrigeration held with Albert Einstein, the patent for a "neutronic reactor"
developed with Enrico Fermi, and Szilard's singular achievements on the "Chain Reaction" and "Chemostat."
C) History: Materials originally gathered together under that title in Mrs. Szilard's inventory. Herein are important retrospective
writings by Szilard on early atomic bomb development and his involvement with the Manhattan Project.
D) Interviews: Dating mostly from the 1960s, and arranged alphabetically by interviewer or by title when no interviewer is
E) Memoranda: General communications not directed to a specific recipient. They are arranged chronologically. Most of these
materials originated in the Metallurgical Laboratory in Chicago.
F) Speeches: Szilard's Speeches date from the close of his direct involvement with the atomic bomb after World War II and
his shift into public life as an advocate of disarmament.
G) Handwritten Notes: Fragments of Szilard's writings, often jottings on a napkin or a loose scrap of paper. These materials
lacked a direct relationship to other items in the original folders in which they were found. The materials have either been
labelled with Mrs. Szilard's original folder numbers (where the items were found) or have been given a subject title.
H) Notebooks: Arranged first by date, then alphabetically by title.
I) Publications by Other Authors: Materials collected by Szilard after he began work in biology. Organized alphabetically
by author, each folder often contains several works.
