Table of Contents
Ralph Baldwin: The Face of the Moon// (1949) & //The Measure of the Moon (1963)
Two highly influential books providing evidence for the meteoritic origin of many craters on the Moon and establishing probably lunar timescales.
Baldwin's views of the Moon were influenced, in part, by his experiences developing fuses for explosives during World War II.
Although professionally trained as an astronomer, Baldwin's main job was running a family owned tool-making company.
The second book (1963) expands on the first (1949), making a much stronger case.
The 1965 book is a text for college students, summarizing both Baldwin's views and those of others.
