Albert Atterberg
Albert Mauritz Atterberg (19 March 1846 – 4 April 1916) was a Swedish chemist and agricultural scientist who created the Atterberg limits, which are commonly referred to by geotechnical engineers and engineering geologists today. In Sweden he is equally known for creating the Atterberg grainsize scale, which remains the one in use. Atterberg received his Ph.D. in chemistry from Uppsala University in 1872 and then stayed there as a lecturer in analytical chemistry until 1877, during which time he traveled across Sweden and abroad to study the latest developments in organic chemistry. He then went on to become the principal of the Chemical Station and Seed Control Institute at Kalmar, publishing numerous papers on agricultural research dealing with the classification of varieties of oats and corn between 1891 and 1900. It was towards the age of fifty-four that Atterberg, while continuing his work on chemistry, began to focus his efforts on the classification and plasticity of so ...

Kurt Atterberg
Kurt Magnus Atterberg (, 12 December 188715 February 1974) was a Swedish composer and engineer. He is best known for his symphonies, operas, and ballets. Biography Atterberg was born in Gothenburg. His father was Anders Johan Atterberg, engineer; his uncle was the chemist Albert Atterberg. His mother, Elvira Uddman, was the daughter of a famous male opera singer. In 1902, Atterberg began learning the cello, having been inspired by a concert by the Brussels String Quartet, featuring a performance of Beethoven's String Quartet No. 8. Six years later he became a performer in the Stockholm Concert Society, now known as the Royal Stockholm Philharmonic Orchestra, as well as publishing his first completed work, the Rhapsody for Piano and Orchestra, Op. 1. His String Quartet No. 1 in D major, Op. 2, soon followed. While already studying civil engineering at the Royal Institute of Technology, Atterberg also enrolled at the Royal College of Music, Stockholm in 1910 with a score of his ...
