notes: label: Description
content: This is one of a group of wooden stands, painted black, which are designed to hold models produced by Ludwig Brill and Martin Schilling. It is a disc-shaped stand (not hollow) with three wooden feet. A paper tag on the model reads: D41,12. A mark in pencil atop the disc reads: #6 (/) Hyperbolic Paraboloid (/) 26 lines sections.
label: Description
content: Ludwig Brill sold, as part of his series of paper models, a model of a hyperbolic paraboloid that had 26 sections. It was his model 26. The stand itself is listed and shown in the catalog as Brill’s number 27 (it has no series number).
label: Description
content: Martin Schilling, Brill’s successor, also sold the model as #6 in the series of paper models. The paper model was Schilling’s number 35. The stand itself had no separate number.
label: Description
content: A model in the collections that has a stand that reads “D41,12” is a model of white plaster model of an octant of the outer shell of a wave surface for refraction in a positive crystal (object 1982.0795.26). An example of Schilling’s paper model of a hyperbolic paraboloid has catalog number MA.304722.19, and it seems likely that the stand is for that model. An example of Brill’s version of the model is 1985.0112.021. However, this Brill model came after the stand.
label: Description
content: There is a model of an optical surface with a paper tag that reads D41,12 (1982.0795.26). However, it is not a hyperbolic paraboloid. See
