Project PHaEDRA - Jenka Mohr - 16th Magnitude Survey, M2 #G118 (phaedra2406)

About the Project

At Harvard College Observatory (now the Center for Astrophysics | Harvard & Smithsonian), Women Astronomical Computers studied glass plate photographs of the night sky. Here they cataloged stars; identifying variables, interpreting stellar spectra, counting galaxies, and measuring the vast distances in space. Several of them made game-changing discoveries in astronomy and astrophysics. In these books, follow the work of Jenka Mohr who studied galaxies, star clusters, and the history of the Observatory's previous directors. Interested in the history of science? Love astronomy? Help us transcribe the work of the Harvard Observatory's women computers and early astronomers and see which stars shine the brightest. PLEASE NOTE: Project PHaEDRA notebooks are quite unique, and we have a special set of instructions for them. Please take a moment to familiarize yourself with these guidelines.

Recently, research material originally produced during the mid-to-late 19th and early 20th centuries by researchers at the Harvard College Observatory was re-discovered within the Harvard Library Depository. Written by the Women Astronomical Computers and the male astronomers, these early notebooks and other materials are absolutely irreplaceable. They represent the history of the Harvard College Observatory and contain remarkable examples of primary source material showing the evolution of observation methods, along with early astronomy as a whole. Some of the historical methods represented here for transforming, correcting, and calibrating data from glass plates are not commonly known to modern astronomers. The documents are also relevant to the history of women in science as the collection contains material produced by the Harvard Computers. Women like Williamina Fleming, Annie Jump Cannon, Henrietta Swan Leavitt, Cecilia Payne-Gaposchkin and Antonia Maury made their mark in astronomy (and history!) at Harvard by studying these glass plates and publishing their findings in their own name. To learn more about the impact of the women computers, listen to an interview with Dava Sobel about her book "Glass Universe" describing their legacy.

Content: handwritten materials, primarily in cursive or somewhat difficult to read (predominantly from the 19th and 20th centuries) , audio recordings that are relatively easy to hear/decipher, and scientific materials
Language: English and/or other languages that use Roman script but may require the use of diacritics (French, Spanish, German, Italian, etc.)
Format: audio recordings, letters, diaries, notes and other written materials, projects with templated fields and special instructions
Subject Area Expertise/Special Skills: some knowledge of non-English Roman-character/script languages and diacritics may be useful, as well as experience reading cursive handwriting. A general knowledge or familiarity with scientific terminology.

Level 5 - ADVANCED
