Friedrich Hasenöhrl (November 30, 1874 - October 7, 1915), was an Austro-Hungarian physicist.
Friedrich Hasenöhrl was born in Vienna, Austria (Austria-Hungary) in 1874. His father was a lawyer and his mother belonged to a prominent aristocratic family. After his elementary education, he studied natural science and mathematics at the University of Vienna under Joseph Stefan (1835–1893) and Ludwig Boltzmann (1844–1906). He worked under Heike Kamerlingh Onnes in Leiden at the low temperature laboratory, and there he also was friendly connected with H. A. Lorentz.
In 1907 he became Boltzmann's successor at the University of Vienna as the head of the Department of Theoretical Physics. He had a number of illustrious pupils there and had an especially significant impact on Erwin Schrödinger, who later won the Nobel Prize for Physics for his contributions to Quantum Mechanics.
When the war broke out in 1914, he volunteered at once into the Austria-Hungarian army. He fought as Oberleutnant against the Italians in Tyrol. He was wounded, recovered and returned to the front. He was then killed by a grenade in an attack on Mount Plaut on October 7, 1915 at the age of 40.
Sir Malcolm Henry Arnold, CBE (21 October 1921 – 23 September 2006) was an English composer and symphonist.
Malcolm Arnold began his career playing trumpet professionally, but by age thirty his life was devoted to composition. He was ranked with Benjamin Britten as one of the most sought-after composers in Britain. His natural melodic gift earned him a reputation as a composer of light music in works such as in some of his concert overtures and the sets of Welsh, English, Scottish, Irish and Cornish Dances. He was also a highly successful composer of film music, penning the scores to over a hundred features and documentaries, including classic titles such as The Bridge on the River Kwai, Hobson's Choice and the St Trinian's series. His nine symphonies are often deeply personal and show a more serious side to his work, which has proved more controversial. Arnold also wrote a variety of concertos and chamber works, as well as music for the theatre including major ballets. His brass music is widely acclaimed.
