C-K design theory or concept-knowledge theory is both a design theory and a theory of reasoning in design.
 It defines design reasoning as a logic of expansion processes, "i.e." a logic that organizes the generation of unknown objects.
 The theory builds on several traditions of design theory, including systematic design, axiomatic design, creativity theories, general and formal design theories, and artificial intelligence-based design models.
 Claims made for C-K design theory include that it is the first design theory that:
Design U is a Canadian television series which premiered on April 4, 2005 on HGTV (Canada).
 Produced by Mountain Road Productions the series takes the design-clueless back to school for a crash course in interior design.
 After one intense day with a professional designer—learning the ins and outs of design theory—the design student gets to test their newly acquired design savvy during a two-day makeover.
 With $3000 and a team of renovators at their disposal, the student has to transform one room in their house.
 At the end, the design professor returns to review the results to see if the student makes the grade.
Raj Chandra Bose (19 June 1901 – 31 October 1987) was an Indian American mathematician and statistician best known for his work in design theory, finite geometry and the theory of error-correcting codes in which the class of BCH codes is partly named after him.
 He also invented the notions of partial geometry, strongly regular graph, and started a systematic study of difference sets to construct symmetric block designs.
Tres Personajes, second version (English: "Three People") was painted by Mexican Modernist artist Rufino Tamayo in 1970.
 The brightly colored 51" by 38" (130 cm x 97 cm) painting is considered to be significant as an example of Tamayo's mature style.
 It is an abstract depiction of a man, a woman and an androgynous figure in a rich palette of purple, orange and yellow, with Tamayo's signature rough surface texture, made of sand and ground marble dust mixed into the paint.
 The artist died in 1991 at the age of 91.
The "Cubi" series is a group of stainless steel sculptures built from cubes, rectangular solids and cylinders with spheroidal or flat endcaps.
 These pieces are among the last works completed by the sculptor David Smith.
 The artist died in a car accident on May 23, 1965, soon after the completion of "Cubi XXVIII", which may or may not have been the last sculpture he intended to create in this series.
 The "Cubis" are among Smith's final experiments in his progression toward a more simplified, abstract form of expression.
 As an example of Modernism, these are representative of the monumental works in industrial materials that characterized much of the sculpture from this period.
John Wood, DipAD, ADF(Manc), FRSA (b. 25 August 1945) is Emeritus Professor of Design at Goldsmiths College, University of London.
 In Professor Geoffrey Crossick's introduction to Wood's inaugural lecture at Goldsmiths, University of London on 21 October 2008, he said that Wood has had "a transforming influence on design theory and practice."
 He taught many Young British Artists when he was Deputy Head of the Fine Art Department at Goldsmiths between 1978 and 1988.
 He has received AHRC and EPSRC funding for research into metadesign.
Paul Klee (] ; 18 December 1879 – 29 June 1940) was a Swiss-German artist.
 His highly individual style was influenced by movements in art that included Expressionism, Cubism, and Surrealism.
 Klee was a natural draftsman who experimented with and eventually deeply explored color theory, writing about it extensively; his lectures "Writings on Form and Design Theory" ("Schriften zur Form und Gestaltungslehre"), published in English as the "Paul Klee Notebooks", are held to be as important for modern art as Leonardo da Vinci's "A Treatise on Painting" for the Renaissance.
 He and his colleague, Russian painter Wassily Kandinsky, both taught at the Bauhaus school of art, design and architecture.
 His works reflect his dry humor and his sometimes childlike perspective, his personal moods and beliefs, and his musicality.
Bishop v. Aronov, 926 F.2d 1066 (11th Cir.
 1991), was a 1991 legal case in which Phillip A. Bishop, an exercise physiology professor at the University of Alabama, sued the college on free speech and academic freedom grounds, when it instructed him not to teach "intelligent design theory" in an extracurricular class and not to lecture on "evidences of God in Human Physiology" in class.
 The District Court for the Northern District of Alabama found in favor of Bishop but the university appealed and the United States Court of Appeals for the Eleventh Circuit found that the classroom, during instructional time, was not an open forum, and that the university had a right to set the curriculum.
Haim Hanani ((1912--) 11, 1912 as Chaim Chojnacki–April, 1991) was a Polish-born Israeli mathematician, known for his contributions to combinatorial design theory, in particular for the theory of pairwise balanced designs and for the proof of an existence theorem for Steiner quadruple systems.
 He is also known for the Hanani–Tutte theorem on odd crossings in non-planar graphs.
Kaitag textiles are an unusual embroidered textile art form from the Kaitag district of southwest Daghestan, Russia, inhabited mainly by Dargins and Kumyks.
 Kaitag textiles are of simple construction, being laid and couched silk-floss embroidery on a cotton ground.
 The designs are often in the style of classical Safavid Persian art, sometimes illustrating horsemen and hunting scenes.
 Abstract Kaitag designs have been compared to those of Matisse and Paul Klee, though it is unlikely that either artist ever saw a Kaitag textile.
 Surviving examples are mostly from the 17th and 18th centuries.
 These embroideries were apparently made for local use in weddings, funerals, and for cradle trappings.The traditional Kaitag art of embroidery was reportedly stamped out under Soviet rule.

Question: When was the Swiss-German artist died who's lecture is "Writings on Form and Design Theory" and who's design had been compared with abstract Kaitag designs?
Answer: 29 June 1940
