Weihnachtsbaum (Liszt) movements from the suite for strings and celesta. Italian composer Giampaolo Testoni has arranged the entire suite for orchestra. Weihnachtsbaum (Liszt) Weihnachtsbaum (English: "Christmas Tree"; French: "Arbre de Noël") is a suite of 12 pieces written by Franz Liszt in 1873–76, with revisions in 1881. The suite exists in versions for solo piano and piano four-hands. "Weihnachtsbaum" does not demand great virtuosity, and it has been described as a distant relation of Schumann's "Kinderszenen" and Debussy's "Children's Corner". It occupies an unusual place in Liszt's output, and it may be for these reasons that it has received relatively little attention
Allen Tannenbaum thesis advisor Heisuke Hironaka at the Harvard University in 1976. Tannenbaum has done research in numerous areas including robust control, computer vision, and biomedical imaging, having almost 500 publications. He pioneered the field of robust control with the solution of the gain margin and phase margin problems using techniques from Nevanlinna–Pick interpolation theory, which was the first H-infinity type control problem solved. Tannenbaum used techniques from elliptic curves to show that the reachability does not imply pole assignability for systems defined over polynomial rings in two or more variables over an arbitrary field. He pioneered the use of partial differential
