William Brock was of Dutch descent; his ancestors came to England as pilgrims or asylum seekers to escape religious oppression in Holland in the 16th century. He began working life as a watchmaker in Hertford at a shop owned by a Mr Field. He lodged nearby with a lay village pastor, whose enthusiasm tempted him to try his skill in such voluntary pastoral work. In due course, Brock gave up his watch-making to become a pastor. He applied to the Baptist College, Stepney, from where he graduated a few years later. He was offered employment at St Mary's Church in Norwich. Here he stayed for fifteen years, though not infrequently travelling to London to support meetings of the non-denominational Missionary Society, which gradually evolved into the non-denominational but largely nonconformistLondon Missionary Society. His links with both Anglicans and Nonconformists may have helped him, in 1848, to be appointed minister of the first purpose-built central London Baptist Chapel - the Bloomsbury Chapel - whose establishment had hinged partly on overcoming objections from the Anglican establishment.
Ministerial life at Bloomsbury Chapel and later
At his Bloomsbury Chapel, which served Central London north of the River Thames, Brock's hearty, low-key, oratorial style was in marked contrast to that being developed at the Baptist chapel on the South Bank by the "crowd-pulling" evangelist, the Rev. Spurgeon. At an ordination service for a missionary, to which both had been invited, Spurgeon noted how extraordinarily different they were: he found Brock's delivery to be "massive, ornate, rich in words, too ponderous for our tongue, and in terms which would have suited none but himself", but, he generously added "it was ’homely, hearty, intense, overwhelming; it did our soul good".
Career as a biographer
Amongst his wider interests, Brock was an active member of the Peace Society pioneered by such figures as Henry Richard. Brock was, therefore, opposed to warfare at the time of the Crimean War and Siege of Lucknow but nevertheless wrote a well-researched biography of the life of General Sir Henry Havelock, who was a fellow baptist. Published in 1857, Brock's departure into contemporary biography achieved an enormous circulation and ran to many popular editions. However, he was widely criticised by those who would not buy his book, including friends in the Baptist ministry and Peace Society, for attempting the portrayal of a Christian who was also a soldier in complex contemporary political and military events. Less controversial was his biography of John Bunyan; it too became a best-seller, bound into many of Cassell's late Victorian editions of Bunyan's works.
Abolitionist
Besides his interests in the work of the Peace Society, albeit somewhat compromised by his controversial biographical writing, Brock was also active as an abolitionist. His name occurs frequently in accounts of meetings held in England during the 1840s, 1850s and early 1860s to support the abolition of slavery in the United States, and pressing for abolition in Josiah's Conder's nonconformist newspaper. At an early stage in this work, he appears as a delegate in the painting of the world's first international Anti-slavery Convention in 1840, which hangs in the National Portrait Gallery in London.
