Salomon de Brosse
Salomon de Brosse
( 1571 – 9 December 1626) was an influential early 17th- century French architect, a major influence on François Mansart.
Salomon was born in Verneuil- en- Halatte, Oise, into a prominent Huguenot family, the grandson through his mother of the designer Jacques I Androuet du Cerceau and the son of the architect Jean de Brosse.
He was established in practice in Paris in 1598 and was promoted to court architect in 1608.
De Brosse greatly influenced the sober and classicizing direction that French Baroque architecture was to take, especially in designing his most prominent commission, the Luxembourg Palace, Paris( 1615- 1624), for Marie de' Medici, whose patronage had been extended to his uncle.
Salomon de Brosse simplified the crowded compositions of his Androuet du Cerceau heritage and contemporary practice, ranging the U- shaped block round an entrance court, as Carlo Maderno was doing at Palazzo Barberini, Rome, about the same time.
The impetus for the plan is often traced to Palazzo Pitti, Florence, where the Medici queen had spent her youth, but the formal plan of Anet could also be adduced.
He clad the building wholly in stone, avoiding the lively contrast of brick and stone that was the more familiar idiom.
Though de Brosse was forced to relinquish his post on 24 March 1624, construction of the Luxembourg proceeded according to his plan and elevations; extensions made in the nineteenth century have not obscured his external elements.
Other buildings that he designed include: De Brosse died, aged 55, in Paris.
Jean III de Brosse
Jean III de Brosse( d. 1502) was Count of Penthièvre from 1480 until his death.
He was the elder son of Jean II de Brosse and Nicole, Countess of Penthièvre.

They had one son, René de Brosse, and four daughters.
