Maertens, William— Cousin of Conrad Carl Von Hamm (1870— 1965); senior partner in the importing firm of Hoffschlaeger & Company.
Builders of Hawaii
CONRAD CARL VON HAMM, Business Organizer. Correspondence about Hawaiian
postage stamps desired by a young German bank clerk for his collection was
responsible for the arrival in Honolulu of Conrad Carl von Hamm and the
subsequent establishment of The von Hamm-Young Co., Ltd.
Anxious to obtain stamps of the Hawaiian Kingdom, Mr. von Hamm, then with
the Bremer Filiale der Deutschen Bank, Bremen, Germany, wrote to William
Maertens, a distant relative, and then senior partner in Hoffschlaeger & Co.,
Honolulu importers. During the exchange of letters Mr. Maertens suggested that
Mr. von Hamm should come to Hawaii. He arrived in 1890, entering the employ of
Hoffschlaeger & Co. at a salary of $60 a month.
During the several years that followed Mr. von Hamm, through diligent
application to his work, received a number of promotions. In 1899, less than
ten years after his arrival, he was offered a partnership by Hoffschlaeger &
Co., but instead of accepting this flattering proposal he decided to launch
into business for himself . . . . .
