He was a descendant of the German noble family von Alvensleben and was the third son of Werner von Alvensleben, later Werner von Alvensleben-Neugattersleben and Anna von Veltheim and had two sisters and four Brothers, including the businessman and politician Werner von Alvensleben and later president of the club Count Bodo von Alvensleben-Neugattersleben. The widow of his dead brother's 1914 Joachim was the abbess of the convent at Heiligengrabe and General Manager of the Protestant mission station Armgard of Alvensleben. On 2 April 1908, he married a teacher in Vancouver Edith Westcott. From this marriage there were three children out: Margret, Gero and Bodo.
Early life
After attending the Institute of Cadets, he initially began a military career that he entered as a lieutenant. He made his unscheduled farewell and migrated to the Americas. This was because after a publicised argument his father no longer wanted to pay a supplementary allowance. After a brief stay in El Salvador, where he was working on the coffee farms of his older brother Joachim, he moved in the summer of 1904 finally to Vancouver - with only four dollars in cash.
Life in Vancouver
First, he worked as a farm laborer, night watchman, fishermen, hunters and sellers of poultry through life, could then buy a boat and after a successful season working on the Fraser River he saved 1500 U.S. dollars. With this money, he continued to make progress forming a real estate and finance company in 1907, which was named Alvensleben Finance and General Investment Company. He switched to credit bilateral large ads in the Vancouver Sun newspaper that he very quickly made known. He was also the cofounder in 1907 of the Vancouver Stock Exchange on which he was active. There on some days more than half the daily turnover were his transactions. His business was assisted by the assumption that as his father was a close friend of Kaiser Wilhelm he was investing his money and representing his business interests. This caused other Germans to wish to invest their funds alongside. In fact most of the Kaiser's investments were in German municipal securities and with the firm of Bleichroder.
The latter was at Issaquah in King County in the U.S. state of Washington. Alvensleben became involved there in a restructuring after the mine through many years of labor disputes had been declared bankrupt. The contemporary accounts stated that the mine facilities have been modernized and more than 500 workers employed. The contemporary chroniclers report that Alvensleben created labor peace with "almost socialistic ideas" he restored it by paying fair wages, humane working conditions and fostering good opportunities for residential care and cooperated sensibly with the unions. The rehabilitation of the mine caused a boom in construction: "In 1913 in Issaquah will be more residential and commercial buildings have been built as in the two decades before". Alvensleben embodied in this time the "American Dream": He had by vigor, vision and entrepreneurial risk-taking within a few years advanced from a simple day laborer to become a millionaire in high finance. Even within his lifetime he was regarded as a legend and is now considered one of the great figures from the pioneering days of British Columbia's views.
The outbreak of the First World War led to an abrupt end of his economic empire. His assets were confiscated as enemy property. He had to escape an arrest, leaving Canada and settling in Seattle. Then in 1917 when the United States entered the war, he became suspected as a "spy". He was arrested by a business associate Marshall Latham Bond. He was held in the internment campsFort Douglas in the state of Utah, from 1920 until he again dismissed. He was acquitted after the war though others in his organization were found guilty. Among his defenders was his arresting officer Marshall Bond. He then worked in real estate business and as a stockbroker in Seattle, but without his previous economic successes, he could not operate on the same scale again. In 1939 he was naturalized as an American citizen.
