In particular, Geoffrey Burbidge, William Tifft and Halton Arp were all observational astrophysicists who proposed that there were inconsistencies in the redshift observations of galaxies and quasars.

Halton Arp continues to maintain that there are anomalies in his observing of quasars and galaxies that serve as a refutation of the Big Bang.

Halton Arp has proposed an explanation for his observations by a Machian " variable mass hypothesis ".

Quasars, Redshifts and Controversies is a 1987 book by Halton Arp, an astronomer famous for his Atlas of Peculiar Galaxies ( 1966 ).

Halton Arp continues to report the existence of apparently connected objects with very different redshifts.

A foundation dedicated to the late Jean Arp, named Stiftung Hans Arp und Sophie Taeuber-Arp e. V., was established in 1977 by the dealer Johannes Wasmuth in consultation with Arp ’ s widow, Marguerite Arp-Hagenbach.

but Leger, Arp, Lipchitz and Alexander Calder, at the time, gave him their blessing.

Before leaving for America, he happened to see his old friend Jean Arp and confided to him his new resolutions.

Surrealists like Hans Arp and Max Ernst might talk of creation by hazard -- of composing pictures by walking on them with painted soles, or by tossing bits of paper up in the air.

Nothing looks anything like an Ernst or an Arp but another Ernst or Arp.

Interest lagged, then picked up in the mid-20th century, as collectors competed for the modern-looking figures that seemed so similar to sculpture by Jean Arp or Constantin Brâncuşi.

Key figures in the movement included Hugo Ball, Emmy Hennings, Hans Arp, Raoul Hausmann, Hannah Höch, Johannes Baader, Tristan Tzara, Francis Picabia, Richard Huelsenbeck, Georg Grosz, John Heartfield, Marcel Duchamp, Beatrice Wood, Kurt Schwitters, and Hans Richter, among others.

In 1916, Hugo Ball, Emmy Hennings, Tristan Tzara, Jean Arp, Marcel Janco, Richard Huelsenbeck, Sophie Täuber, and Hans Richter, along with others, discussed art and put on performances in the Cabaret Voltaire expressing their disgust with the war and the interests that inspired it.

As well as the main members of Berlin Dada, Grosz, Raoul Hausmann, Höch, Johannes Baader, Huelsenbeck and Heartfield, the exhibition also included work by Otto Dix, Francis Picabia, Jean Arp, Max Ernst, Rudolf Schlichter, Johannes Baargeld and others.

In Cologne, Ernst, Baargeld, and Arp launched a controversial Dada exhibition in 1920 which focused on nonsense and anti-bourgeois sentiments.

Van Doesburg mainly focused on poetry, and included poems from many well-known Dada writers in De Stijl such as Hugo Ball, Hans Arp and Kurt Schwitters.

The LTM label has released a large number of Dada-related sound recordings, including interviews with artists such as Tzara, Picabia, Schwitters, Arp and Huelsenbeck, and musical repertoire including Satie, Ribemont-Dessaignes, Picabia and Nelly van Doesburg.

He showed two Abstraktionen ( semi-abstract expressionist landscapes ) at Walden's gallery Der Sturm, Berlin, June 1918, which led directly to meetings with members of the Berlin Avant-garde, including Raoul Hausmann, Hannah Höch and Hans Arp in the autumn of 1918.

Whilst Schwitters still created work in an expressionist style into 1919 ( and would continue to paint realist pictures up to his death in 1948 ), the first abstract collages, influenced in particular by recent works by Hans Arp, would appear in late 1918, which Schwitters dubbed Merz after a fragment of found text from the sentence Commerz Und Privatbank in his picture Das Merzbild, Winter 1918 – 19.

Though not a direct participant in Berlin Dada's activities, he employed Dadaist ideas in his work, used the word itself on the cover of Anna Blume, and would later give Dada recitals throughout Europe on the subject with Theo Van Doesburg, Tristan Tzara, Hans Arp and Raoul Hausmann.

In many ways his work was more in tune with Zürich Dada's championing of performance and abstract art than Berlin Dada's agit-prop approach, and indeed examples of his work were published in the last Zürich dada publication, der Zeltweg, November 1919, alongside the work of Arp and Sophie Tauber.

He started to organise and participate in lecture tours with other members of the international avant-garde, such as Hans Arp, Raoul Hausmann and Tristan Tzara, touring Czechoslovakia, Holland, and Germany with provocative evening recitals and lectures.

Merz 5, 1923, for instance, was a portfolio of prints by Hans Arp, Merz 8 / 9, 1924, was edited and typeset by El Lissitsky, Merz 14 / 15, 1925, was a typographical children's story entitled The Scarecrow by Schwitters, Kätte Steinitz and Theo Van Doesburg.

His work in this period became increasingly Modernist in spirit, with far less overtly political context and a cleaner style, in keeping with contemporary work by Hans Arp and Piet Mondrian.

Curt Valentin began exhibiting Marini ’ s work at his Buchholz Gallery in New York in 1950, on which occasion the sculptor visited the city and met Jean Arp, Max Beckmann, Alexander Calder, Lyonel Feininger, and Jacques Lipchitz.
