Andrew Smith Hallidie
Andrew Smith Hallidie (March 16, 1836–April 24, 1900) was the promoter of the Clay Street Hill Railroad in San Francisco, USA. This was the world's first practical cable car system, and Hallidie is often therefore regarded as the inventor of the cable car and father of the present day San Francisco cable car system, although both claims are open to dispute. He also introduced the manufacture of wire rope to California, and at an early age was a prolific builder of bridges in the Californian interior.
== Early life ==
Andrew Smith Hallidie was born Andrew Smith, later adopting the name Hallidie in honor of his uncle, Sir Andrew Hallidie. His birthplace is variously quoted as London in the United Kingdom. His father, Andrew Smith, had been born in Fleming, Dumfrieshire, Scotland, in 1798, and his mother, Julia Johnstone Smith, was from Lockerbie, Dumfrieshire.〔(www.sfmuseum.org Andrew Smith Hallidie )〕
The younger Smith was initially apprenticed to a machine shop and drawing office. In 1852 both father and son set sail for California, where the father had an interest in some gold mines in Mariposa County. These proved disappointing, and the father returned to England in 1853. The son, however, remained in California, and became a gold miner whilst also working as a blacksmith, surveyor and builder of bridges.
In 1856, whilst working on the construction of a flume at a mine at American Bar, Hallidie was consulted over the rapid rate of wear on the ropes used to lower cars of rock from the mine to the mill. These ropes were wearing out in 75 days. Hallidie improvised machinery to make a replacement wire rope, which lasted two years, and in the process began wire rope manufacture in California.
