Chemex Coffeemaker
manual pour-over style glass coffeemaker, invented in 1941

The Chemex Coffeemaker is a manual pour-over style glass coffeemaker, invented by Peter Schlumbohm in 1941, manufactured by the Chemex Corporation in Chicopee, Massachusetts.
In 1958, designers at the Illinois Institute of Technology selected the Chemex Coffeemaker as "one of the best-designed products of modern times." It is included in the collection of the Museum of Modern Art in New York City. It has been featured in the novel From Russia with Love, in a scene where James Bond eats breakfast, the film Harper starring Paul Newman, The Mary Tyler Moore Show, and Ira Levin's Rosemary's Baby, as well as its film adaptation.
Design
The Chemex coffeemaker consists of an hourglass-shaped glass flask with a conical funnel-like neck and proprietary filters, made of bonded paper, that are thicker than the standard paper filters used for a drip coffeemaker. The thicker paper of the Chemex filters removes most of the coffee oils and makes coffee that is much "cleaner" than coffee brewed in other coffee-making systems. The thicker filter papers may also assist in removing more cafestol, a cholesterol-elevating compound found in coffee.
The most visually distinctive feature of the Chemex is the heatproof wooden collar around the neck, which allows it to be easily handled and poured when full of hot coffee. The collar is turned and then split in two to allow it to fit around the glass neck. The two pieces are held loosely in place by a tied leather thong. For a design piece that became popular post-war at a time of Modernism and precision manufacture, this juxtaposition of natural wood and the organic nature of a hand-tied knot with the laboratory nature of glassware was a distinctive feature of its appearance.

Why this record matters
The phrase “manual pour-over style glass coffeemaker, invented in 1941” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jul 4, 2026. The linked authority identifier is Q5090371. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1941 and 1958.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
