CLICK). Margaret Sarah Carpenter's fine portrait Augusta Ada Byron (1836) was painted to celebrate her marriage to William King, a baron, who became Earl of Lovelace two years later. So Ada became The Right Honourable the Countess of Lovelace. Hence her modern name. In her stately gown she doesn't look nerdy enough to be a computer programmer. No spectacles. No beard. No jeans. No T-shirt with a silly slogan on the front. This beautiful oil painting belongs to the British Government Art Collection and is currently in 10 Downing Street. So you need to be one of David's old Etonian chums or a corrupt media mogul to view it in all its glory.
