Bowyer’s father, a lawyer from Somerset, settled in Camberwell on his marriage to the daughter of Robert Draper, a minor court official, and became a bencher of Lincoln’s Inn. Bowyer also qualified as a barrister and retained his chambers till his death, sharing them for a period with Sir Roger Owen*, though he does not seem to have practised. In the early 1580s he purchased substantial property in the Camberwell area and the following decade established himself as a significant figure in Surrey local administration, helping, for instance, to administer the county’s composition for purveyance.
Bowyer was elected for Morpeth in 1593, the first of the family to be returned to Parliament, and represented Southwark in 1597. He may have owed his election as knight of the shire for Surrey in 1604 to the support of the lord lieutenant of the county, the 1st earl of Nottingham (Charles Howard†). Bowyer was appointed at least twice to investigate slanderous words that had allegedly been spoken against Nottingham in the late Elizabethan period, suggesting that he was connected in some way to the earl.
Bowyer received 64 committee appointments in the first Jacobean Parliament, 22 of them in the first session. He was appointed to attend two conferences with the Lords about wardship, on 26 Mar. and 22 May, and on 3 Apr. was among those instructed to consider a bill for the better execution of the laws against purveyors.
Bowyer’s previous involvement in the London building trade probably explains his appointment to consider a bill on that subject on 27 April.
In the second session, Bowyer was among those instructed on 22 Jan. 1606 to consider the best means of providing a learned and resident ministry.
On 30 Oct. 1606 Chancery appointed Bowyer, together with George Rivers*, to examine the parish accounts of St. Saviour’s, Southwark as part of a continuing lawsuit between the select vestry and an opposing group among the local inhabitants. The following December the critics of the vestry, presumably perceiving Bowyer and Rivers as sympathetic to their cause, tried to refer seven articles detailing further grievances to the commissioners, but were blocked by the vestry.
Bowyer was named to a further ten committees in the third session. Once again these included committees on bills to halt new building in London (8 Dec. 1606) and to regulate watermen (3 Mar. 1607).
Early in 1610 Bowyer joined in the local protest against a project to supply London with water from the River Wandle in Surrey.
In October 1613 Bowyer was sued by the Virginia Company for failing to pay £37 10s. which he had subscribed three years earlier.
The following year Bowyer was appointed one of the first governors of Camberwell grammar school, and in 1619 he was present at the formal opening of Dulwich College, the foundation of his neighbour Edward Alleyn.
Bowyer did not sit in the third Jacobean Parliament, but was returned for Gatton in 1624, presumably with the support of the earl of Nottingham, who had significant influence in the borough, and William Copley, the Catholic lord of the manor to whom Bowyer was related by marriage.
Bowyer drafted his will on 11 July 1626. He had asked to be buried in the chancel of Camberwell Church, near to his wife, ‘and that to be done in the day time, my body not to be bowelled, but to go to the earth as I came into this world, and with such decency as fitteth the honour of a knight’. He was generous to the poor of Camberwell and other parishes, left a mourning gown and £5 to his chaplain Edward Wilson as well as a mourning gown to the vicar of Camberwell and £5 to the lecturer. Having no children of his own his nephew Edmund, who was elected for Gatton in 1660 and Surrey in 1661, succeeded to the Camberwell property and to his books, both in his home and in his study at Lincoln’s Inn. He died the following February.
