Russian-readers will be richly rewarded, given that Dobzhansky modulates entries between Russian and English. In some entries, he self-consciously reflects on the language he opts to use. For example, on February 16, 1952, he imagines his child (Sophie) as the audience of his entries: "I am switching to English, in order that my child would find it easier to accompany her father's experiences, is she wants to accompany them."
 
Even in diaries recorded predominantly in Russian, Dobzhansky encloses numerous ephemera—business cards, letters, hand-drawn sketches, recognitions/awards, medical test results, newspaper clippings, and more—accessible to English-speakers. In many of his diaries from the 1950s and 1960s, typed letters provide some insights into his thoughts on health, mortality, and faith (e.g. 2/16/1952, 5/16/1957, 7/16/1968, 10/13/1969)
 
(strained) relations with his children (e.g. 5/16/1957, 10/28/1968, 12/31/1968)
 
and career (3/25/1970
 
6/30/1970, 1/25/1975).
 
Dobzhansky traveled widely, providing particularly detailed accounts of South America and the American West. While English entries largely abstains from discussing politics, he does occasionally discuss Brazilian politics (e.g. 9/7/1954, 10/16/1955), and the election of Richard Nixon, about whom he is consistently critical (e.g. 11/6/1970, 12/31/1973, 8/8/1974).
 
Throughout his four decades of journal-writing, Dobzhansky expresses one consistent concern: his desire to continue doing useful work. Marking his final birthday, he writes, "So, I have lived ¾ of a century. Today begins the last quarter, or rather past thereof…Oh God, give me power to finish my life serving you by doing my life work in science! In 75 years I have not yet exhausted either my interest or, I hope, my ability" (1/25/1975).

The Dobzhansky Papers feature 47 volumes spanning 1934-1975. (The boxes in which they are enclosed also include other notebooks and workbooks without sequential entries.) These diaries ought to interest researchers studying genetics and evolutionary biology, early-twentieth-century travel expeditions (particularly into the Amazon), the creationist debate (especially in textbooks and public schools), the post-war university (Columbia University, in particular), South American politics, and Dobzhansky's biography.

The Heiser diaries are without peer when it comes to their scope--spanning the first seven decades of the twentieth-century--global reach, and detail. Scholars exploring the history of medicine might gravitate towards entries related to his public health work in the Philippines (1908-1916). Researchers interested in the history of zionism will be richly rewarded by volumes from 1922 and 1926--an excerpt from Heiser's July 1922 journey to Palestine is excerpted in Selected Quotations. And those interested in colonial India will discover a numerous reflections on Gandhi and 1920s non-violent resistance movements (also excerpted in Selected Quotations).
 
Perhaps most surprising are Heiser's detailed accounts of European travel between the 1920s and 1930s, during which he expresses some sympathy for nationalist movements. Traveling war-torn Italy, he remarked on there "appears to be unanimous agreement among natives and foreigners" that the new prime minister, Benito Mussolini, "has accomplished extraordinary results and that he is honest and genuinely patriotic" (11/19/1923). Several years later, he documents the nation's progress in developing infrastructure and improving services. He concludes his 4/29/1926 entry with an ominous justification for fascism: "Democracy gradually became so inefficient that all came to a standstill and a dictator was able to start the machinery on an effective basis."
 
Heiser traveled widely during the decade preceding World War II. In the late-1930s, he returned to Italy and decries the ubiquitous military presence, government propaganda, and oppressive taxation. And yet, he ends his entry with a section entitled "The Other Side." Heiser writes: "A whole new social order has been created. Instead of people finding fault with what government fails in, the press and government propaganda constantly drive into their ears what government is doing for the people. (In the end will this not produce more peace of mind and happiness than our democratic way of emphasizing fault-finding)" (4/25/1937).
 
On the topic of promoting public happiness, Heiser draws a similar conclusion during a contemporaneous visit to Germany. While he decries the Nazi government's "censorship, prohibitions and [intrusion into] one's private affairs," he adds: "And yet one begins to wonder whether there is not much to be said in favor of the good type of dictatorships, in promoting human happiness. In democracies people are [annoyed] to say or think little of the good things government does for them and to place main emphasis upon petty fault finding" (6/3/1937). Finally, just one year prior to the outbreak of World War II, Heiser pens perhaps his most generous account of dictatorships. That account, "Further Impressions Dictatorships," is excerpted in Selected Quotations.

By any measure, public health leader Victor George Heiser lived a long, productive, and vigorous life. His 86 diaries (1890-1972) predate the Spanish-American War and post-date U.S. escalation in Vietnam, while his career in public health put him in contact with politicians, diplomats, ambassadors, and government officials across the globe. An astute political observer, Heiser offers rich, on-the-ground insights into twentieth-century history as it unfolded, from the rise of Gandhi to the fall of Hitler. His 1920s and 1930s entries also offer candid explanations of and justifications for dictatorship. The Heiser diaries may interest a wide range of scholars, including those researching the history of science, American public health policy in the Philippines, the history of Zionism and Israeli statehood, colonialism in Asia (most especially India), and Europe between World War I and World War II.

Morley's early diaries provide intimate accounts of personal affairs, including his romantic relationships and education at Harvard University. In addition to documenting his budding relationship with Alice Williams, whom he would marry in 1908 and divorce in 1914, Morley writes at length about the planning of his first field trip to the Yucatan (1906-07). During that trip, he provides rich accounts of Havana (2/4/1907), Uxmal (2/15/1907), and his first excavation (8/19/1907).
 
Starting in 1912, his diary takes on a closer resemblance to a field notebook, with detailed accounts of his excavations in Belize, Guatemala, Honduras, El Salvador, and Mexico. Interspersed in those records are fascinating accounts of the World War I and World War II, including oblique references to Morley's espionage work. For example, on January 9, 1914 he writes of a "curious telegram warning" from Washington: "'Make no affiliations in the C.matter. This is a danger signal. Await further advices.' I cannot imagine what this can mean. Is it a warning against H.? I sent the following reply: 'Have made no affiliations whatever. Will make none. Will preserve absolute secrecy and keep free from all entanglements. My case is in your hands. Am awaiting further instructions.' Think I will hear by Monday."
 
As the war unfolded, Morley recorded its effects in both Central and South America, including President Woodrow Wilson's "destructive" policy in Mexico (2/13/1914), the geopolitical scramble for Guatemala, and the "key-stone of the arch between the Rio Grande and the canal" (12/8/1917). Later, at the outset of World War II, Morley notes Japanese encroachment on the Dutch East Indies (2/19/1941), and even the attack on Pearl Harbor, "a series of shots that literally were heard around the world" (12/29/1941).
 
In fact, war proves disruptive for Morley's work. A colleague, Dr. Moise La Fleur, is killed during a Mexican chicleros attack (5/17-19/1916), an incident from which Morley does not soon recover. Moreover his excavation of Chichen Itza is badly delayed until 4/28/1924.
 
Nevertheless, researchers interested in both the history of South America and the field of archaeology will be rewarded with meticulous descriptions of excavations conducted between the 1920s-1940s.

The 39 volumes of Sylvanus ("Vay") Griswold Morley diaries span 42 years of the first-half of the twentieth century, and provide textured accounts of Morley's personal affairs, archaeological expeditions in Central and South America, and developments of World War I and II in South America. Morley began keeping a journal while he was in school (1905) and continued maintaining it until 1946, a year before his death the year before his death (1947). Notably, all entries are typed, enabling researchers to quickly scan volumes for specific interests.
