This series contains Oscar Bluemner's scattered personal and professional correspondence, over half of which is in German, and all letters written prior to 1904 are in German. Early correspondence is with his family and with close friend Oscar Klein. Other correspondence is with fellow artists George Ferdinand Of, Edward Bruce, Stefan Hirsch, Ernest Fiene, and Arnold Friedman and with art collectors and patrons Aline Liebman, Ludwig Vogelstein, Margaret Lewisohn, Albert Rothbart, and Walter Hochschild, primarily discussing the purchase of Bluemner's work. Many of these letters are annotated by Bluemner with notes regarding the correspondent and how he met them. Of note are letters from art dealer Stephan Bourgeois, and two letters from Alfred Stieglitz (1919 and 1927). Additional letters are from the Whitney Studio (later the Whitney Museum of American Art) regarding the purchase and exhibition of his work, and letters from other galleries and museums regarding the possibility of exhibiting his work. There is a small amount of correspondence between Bluemner and art historian and friend John Davis Hatch, and a typescript of "An Open Letter and A Private Opinion" (1932) which Bluemner sent to various people and publications.

Correspondence is arranged chronologically, followed by annotated envelopes which originally contained some of the letters, but were separated at some point prior to processing.

This series contains writings by Bluemner which he called "Painting Diaries" and "Theory Diaries". All of the diaries dated after 1918 are unbound and consist of loose pages of notes which were often compiled by Bluemner into "diaries" at a later date. Diaries contain very little discussion Bluemner's everyday life. Portions of the diaries are written in German.

The Painting Diaries generally contain notes on Bluemner's newly-finished paintings or current work. The notes are illustrated and include technical discussions of his work. Bluemner's Theory Diaries include notes on art theory, such as color, form, line, and space. Many are illustrated in color. They address what he referred to as the painting "problem." The Theory Diaries date only from 1919 to 1925. Additional similar writings dating after 1925 are found in Series 4: Writings & Notes.

Diaries are arranged chronologically. Most of the diaries are preceded by a large manilla envelope, originally containing the diary, on which Bluemner wrote the subject of the diary, dates, and additional notes. Some of the envelopes were separated at an earlier date and are not matched to any particular diary. Portions of the diaries are not numbered and every attempt has been made to keep the pages in Bluemner's original order. Additional writings are found in Series 4: Writings & Notes. The diaries have been separated because of their special designation by Bluemner. In reality, there is little difference between the "diaries" and some of the additional writings in the other series.

Found in this series are Oscar Bluemner's extensive writings and notes about his paintings and techniques, and his views on art history and art theory. Included are various lists, essays, notes, and notebooks, many of which also include sketches and color illustrations as well as printed material which Bluemner attached to his notes.

Among the writings is Bluemner's "List of New Sketches and Notes for New Work" in which he recorded his paintings from the early 1930s. Each painting is documented with a record number, date, and sketch, along with detailed notes on the color and composition. There are additional lists of works of art, all written by Bluemner, including a list of his works in a Bourgeois Gallery show in 1921. Also found here are writings for publications and lectures including a "Foreword" for an unidentified publication and an essay for a 1927 Georgia O'Keeffe exhibition catalog, titled "A Painter's Comment", which he annotated at a later date.

This series also includes a group of notes and homemade notebooks on Bluemner's painting techniques, many of which he identified as "Easel Notes" because he kept them in his studio as painting manuals. The notes discuss materials and techniques for watercolor, oil painting, and casein painting, and procedures for framing and shipping his works. Also found within the notes are Bluemner's theories, instructions, formulas, illustrations, and material samples.

Bluemner's writings include his notes about artwork by other artists and paintings and artwork in museums, including the Metropolitan Museum of Art and the Museum of Fine Arts, Boston. He created four volumes of notes taken during a tour of Europe in 1912, all of which are dated and arranged by European city. Many of the notes include detailed sketches.

Bluemner maintained extensive notes on Chinese and Japanese art history and styles. Included among these notes are annotated clippings and reproductions, as well as sketches, drawings, and watercolors of paintings he had seen in books and at museums. Additional annotated books & catalogs are found in Series 5.

This series contains a large collection of interesting and complicated notes Bluemner described as "criteria for new work extracted from all note-folios for a book on painting." He pulled notes from his diaries, procedure and easel notes, lists, etc. and reorganized them around 1934. The notes document many of his complex art theories including the concept of "Ponere" which he defined as "to pose, to place in a space", and this term is used throughout his writings. Also discussed are line, space, materials, sources for paintings, and color theory. They include prose, lists, sketches and illustrations, color and material samples, and news clippings. He often used complicated color coding, abbreviations, and symbols to organize his ideas. Of particular interest among the notes is Bluemner's "Pocket Book on New Work" written in 1934 ( Box 3, folder 27) as a "compendium of all folios written." Some of these notes are in German and Latin.

Writings and notes are arranged according to Bluemner's original arrangement. Folder titles in quotation marks are Bluemner's original titles for his writings; titles in brackets were created by the archivist. Most of the categories of material are preceded by an envelope, originally containing the items, on which Bluemner wrote a title for the contents, dates, and extensive notes. Additional envelopes are found in the last folder of this series and include envelopes with a note stating that the contents were destroyed in 1936. It is believed, based on notes on the envelopes, that Bluemner rearranged these papers and removed certain items while he was preparing to give them to John Davis Hatch. Every attempt has been made to keep the pages in Bluemner's original order.

Bluemner defined many of his groups of sketches and notes as either "Travel Sketches" or "Art Motifs". Many of these were developed into themes for his paintings. The folder titles listed below are Bluemner's own titles and definitions, such as "Alley", "Central Port", or "House & Mountain." The most extensive motif found here is "Trees" consisting of sketches and notes on various types of trees, including notes on the compositional layout of trees in his paintings. Bluemner also had art motif files of travel sketches of various places, mostly of towns in New Jersey, where he lived, but also of Italy, which he visited in 1912. Additional sketches of these same places are found among other files of art motifs.

There is a group of sketches Bluemner called "Mixed Themata." Other terms he used to label this same material are "Very Valuable" and "Vermilion Themata." The items found here are the same types of sketches as the rest of his motif files, and some are labeled as "copies." It appears from his notes, found among these items, that these sketches and notes were pulled from his files of motifs and reorganized, perhaps because they were of greater importance to him. They were sorted by Bluemner according to his own coding system or set of abbreviations.

The files include pencil, charcoal, and colored sketches, most of which are heavily annotated with notes about color and composition. Other items found in the files may include newspaper clippings of images related to the motif, and original file tabs and file dividers which Bluemner created. Bluemner recorded the date and place on almost all of the sketches.

Art motifs and travel sketches are arranged alphabetically by subject according to Bluemner's original arrangement. Most of the categories of material are preceded by an envelope, originally containing the items, on which Bluemner wrote a title for the contents, dates, and extensive notes. It is believed, based on these notes, that Bluemner rearranged these papers and removed certain items while he was preparing to give them to John Davis Hatch. Researchers should be aware that items are generally not in chronological order, and every attempt has been made to keep the pages in Bluemner's original order.
