John Alexander Macdonald was born in Glasgow,Scotland,January 10th,1815,the son of Hugh Macdonald and Helen Shaw (Johnson).His family immigrated to Kingston,Upper Canada along with him in 1820 when he was about 5 years old.
In 1830,John A.Macdonald took an inconspicuous place in the office of George Mackenzie in Kingston as an apprentice.He lodged and boarded with the George Mackenzies; and,despite his gifted skills in article,he was still very much of an ordinary schoolboy,dependent upon authority and direction,hard to waken in the morning,and watched over by Mrs.Mackenzie with kindly solicitude.He was at work all day,and at night,he started to read law in a tight routine of studying under his master’s benevolent direction (John A.Macdonald,21 and 22).
Eventually,all his hard works had paid off – he started his own lawyer office in Kingston,and became quite a successful and quick-witted trial lawyer.Later,He was named as the solicitor for both of the Kingston’s banks (Johnson).
John A.Macdonald married to Isabella Clark on September 1st,1843.His private life has became nothing but sorrow and tragedy after the death of his first son who lived for only 16 months; and after the birth of his second son who survived to adulthood,his wife started weakening and finally died years later in 1856.His sorrowful private life forced him into drinking heavily.Eventually,his private life and his habit of drinking have merged into,no doubt,the biggest weakness in his life.
Before John A.Macdonald became a drunkard,his brilliance had not only shined in the world of lawyers but also the world of politicians.His introduction to politics came in 1843 when he served as a city alderman (Canada’s Prime Ministers).The following year,he entered the Legislative Assembly of the Province of Canada as a Conservative representative for Kingston,acting as receiver-general (Canada’s Prime Ministers).In 1867,the month after John A.drafted the British North America Act,he was elected to be the first Prime Minster of the Canada.
John A.married a second time,to Susan Agnes Bernard in the same year that he was elected to be the Prime Minister.Their joy over a birth of a daughter in 1869 was mitigated by the fact that she suffered from hydrocephaly,which caused both mental and physical handicaps (Canada’s Prime Ministers).Three months after having the fourth consecutive electoral victory in 1891,John A.Macdonald died by a series of stroke in Ottawa,June 6th,1891,and his body was trained back to Kingston later.
