Abraham Schiffmann (07-05-1890 - ?) French composer

Abraham Schiffmann
[Thèmes 64 1961 No.21 p.322]

Abraham Schiffmann is not to be mistaken for Israel Abraham Schiffmann, the Romanian composer and twomover genius, who died in 1930.
Abraham Schiffmann was born in the region of Lviv, Ukraine. He was a direct mate composer of modest talent in comparison with his namesake. He composed mostly threemovers and selfmates and was fond of complete blocks. In 1961 his production was estimated at about 1650 problems (for more details and 6 of his problems, read Thèmes 64 1961 No.21 p.322).

[diagrammes 25, Jan-Feb 1977]

Roger Diot was specialized in three- and moremovers. He was an International Judge in that field.
Between 1968 and 1971 he wrote long articles dedicated to the twomover themes A, B, C, D and E in the magazine "Problème". He collaborated with the French magazine "Thème 64", was the editor of the problem supplement of "L'Échiquier de France", and was also interested in retroanalysis (from the point of view of the logic combination).

After his death, the French magazine "Diagrammes" published the book "Avant-plan" about strategic multimovers with fore-plan. The author himself did not think it would ever be published.
He had also published this book with co-authors Kardos and Authier about Mutates:

Gady Costeff is the author of more than 80 studies, but he is also the co-author of more than 30 problems in all genres, mostly in collaboration with Ofer Comay and Paz Einat. He is the director of the endgame studies magazine EG.
He has written an article, in a typically modest, tongue-in-cheek style, about his efforts at composing problems in all genres with Paz and Ofer. The article can be read here.

The scope of his talent can be discovered browsing through his studies on his website.
On this page presenting studies achieving the Valladao task, Gady Costeff has 2 examples, of which one is considered the "Letztform" of the perfect Valladao.

One of his most amazing studies is the following:
