Probably one of the wealthiest Cambridge townsmen of the first half of the fifteenth century, Bush enjoyed an income of £10 p.a. according to a tax assessment of 1436.
Bush was elected to his only known Parliament while serving his first term as one of the bailiffs of Cambridge. He appears to have attended the Commons of 1422 assiduously, for he spent 45 days away from Cambridge for a session lasting just 40. The borough paid him and his associate, Simon Rankyn*, a daily wage of 2s., so they each received £4 10s. in total. In addition, the two MPs received 10s. for the expenses they had incurred while they and several members of Cambridge’s ruling common council were negotiating in London with Bishop Wakeryng of Norwich about a dispute between the town and the bishop.
Not long before he himself attained the mayoralty, Bush may have become caught up in quarrels arising from the rivalry in Cambridgeshire between John, Lord Tiptoft†, the established magnate in the county, and the young Sir James Butler, afterwards earl of Wiltshire and Ormond. When Henry Brokesby, one of Butler’s tenants at Fulbourn just outside Cambridge, clashed with the Tiptoft following during the early 1440s, he counted among his own supporters Richard Bush of Cambridge. In records relating to that dispute, however, this Richard features as an ‘ostler’, a seemingly unlikely occupation for a burgess of his status.
In November 1445 Bush was associated with his successor as mayor, Richard Wright*, in obtaining various plots of ground from the university, to provide for a common highway.
