Harry johnston was born in London on June 12th 1858. He had two older step-brothers from his father's first marriage, and was himself the eldest of twelve children born from the second. His father, John Johnston, was the well-to-do Secretary of a large insurance company, a shrewd, well-informed, widely travelled man of business, whose work took him regularly all over Western Europe and Scandinavia, and occasionally as far afield as Russia, Asia Minor and South Africa.
