Peter Chamberlen the third

[10] John More, who joined the Lothbury Baptists, provoked a 1652 disputation, spread over several occasion, between Chamberlen and James Cranford, an orthodox presbyterian minister.

[11] He later led a Lothbury congregation that was considered a stronghold of the Fifth Monarchists, and included John Spittlehouse; his own views were taken to be General Baptist.

[15] In 1659 he debated Sabbatarianism with Jeremiah Ives, a General Baptist radical, at the Stone Chapel near St Paul's Cathedral.

[16] Speaking of his political views of the mid=1650s, Toon classes Chamberlen as a Fifth Monarchist, in agreement with Christopher Feake and Nathaniel Rich.

[19] Chamberlen's biographer James Hobson Aveling wrote that his "religious exaltation" of later life verged on mental illness.

[8] A Voice in Rhama, or, The Crie of Women and Children (1647) was Chamberlen's work of advocacy for the professionalisation of midwives, along lines pushed by older members of his family.

[8] A generation earlier, in 1616. midwives had asked the College of Physicians for permission to organise themselves, a petition forwarded and possible prompted by Peter Chamberlen the younger.

His 1647 effort was opposed by the College of Physicians, and was no more successful than the two previous attempts to bring the licensing and control of midwifery under the Chamberlens.

[23][24] He advocated widespread nationalisation, as did Gerrard Winstanley, the Digger; but differed in defending private property and existing economic arrangements.

[27] For his social schemes, of a utopian flavour, Samuel Hartlib, Pieter Corneliszoon Plockhoy and John Jubbes have been suggested as possible influences.

[29] Christopher Hill commented on this "medical radical" and Margaret James's assertion, that Chamberlen, Balthazar Gerbier and Hartlib were the only writers of the time seriously concerned with "the lot of the poor", adding Plockoy to the list.

Another son, Paul (1635–1717), was a quack doctor well-regarded in his time, now remembered for his "anodyne necklace" which, he claimed, could promote healthy pregnancy and easier labour, and ward off the dangers of teething when worn by the child.
