Born Jan. 4, 1643 ("Isaac Newton Biography"). Isaac Newton was born in Woolsthorpe Manor to Hannah and Isaac Newton. Isaac Newton Sr. had died in October, before Isaac Newton Jr. was born (Christianson 10). Isaac Newton Jr. was born an hour or two after midnight, and premature ("Isaac Newton Biography"). Two servants were sent out to fetch medicine for him, but they didn’t believe he would survive until they got back, so they decided to dawdle. However, he did survive (Christianson 10).
