His father, a native of Minden in Westphalia, was a member of Lloyd's, and the young Niemann entered that establishment as a clerk at the age of thirteen.
A number of his paintings sre held by the Woverhampton Art Gallery
He died suddenly on Brixton Hill of apoplexy near his home "The Glebe"
Between 1844 and 1872, he exhibited paintings at a wide range of prestigious galleries including the Royal Academy, the British Institution, the Society of British Artists in Suffolk St, the Royal Scottish Academy, the Royal Institute, the Glasgow Institute, and the Paris Salon. He returned to London in 1848 for the foundation of the 'Free Exhibition' held in the Chinese Gallery at Hyde Park Corner. In 1850 this became the Portland Gallery, Regent Street, and he became its Secretary.
Many of his works were exhibited at the opening of the Nottingham Museum and Art Galleries in 1878. The Victoria and Albert Museum has a landscape by him, Amongst the Rushes, and four drawings in watercolours. A View on the Thames Near Maidenhead is in the Walker Art Gallery, Liverpool.
His son, Edward H. Niemann, was also a successful painter imitating his father's style. Their work is often confused.
