 Kolar was born in Budapest and studied at the Prague Conservatory, where he was a pupil of Otakar Ševčík (violin) and Antonín Dvořák (composition).
 From 1905 until 1920 he was a violinist with the Pittsburgh Symphony and New York Symphony, joining the Detroit Symphony in 1920 as an assistant conductor.
 He remained with the orchestra until 1941, eventually assuming the post of principal conductor.
 Active as a composer as well, he wrote a symphony, some tone poems and a few orchestral suites. Of these last, his "Americana" won first prize in a 1914 contest sponsored by the Illinois State Teachers Association.

 In 1999, Venus acquired WinterSilks, a large importer of silk fashions.
 In 2000, reflecting the expanded offerings, the company name changed to Venus.

John Philip Sousa ( ; ; November 6, 1854 – March 6, 1932) was an American composer and conductor of the late Romantic era, known primarily for American military and patriotic marches.
 Because of his mastery of march composition, he is known as "The March King", or the "American March King" due to his British counterpart Kenneth J. Alford also being known by the former nickname.
 Among his best-known marches are "The Stars and Stripes Forever" (National March of the United States of America), "Semper Fidelis" (Official March of the United States Marine Corps), "The Liberty Bell" (used as the theme for Monty Python's Flying Circus), "The Thunderer" and "The Washington Post".
The Transit of Venus March is a march scored for military brass band written by John Philip Sousa in 1883 to celebrate the 1882 Transit of Venus and published by the J.W. Pepper Company.
 The work was erroneously thought to be lost for over 100 years when a piano transcription published in 1896 was found by a Library of Congress employee in 2003.
 Copies of the original Pepper publication, however, do survive.
