A ballad about him is very informative:

Dr. William Price

The Ballad of Doctor Price.
Composed by Meic Stephens in the 1960's.
Nowadays, it would be considered politically incorrect, in particular the references to illegitimacy & ‘bugger’.
But in the 60's, it could have been considered avant-garde in many ways, if not a lot of fun!!
I suppose the change is a part of history.

There once was a man called Dr. Price
Who lived on lettuce, nuts and rice
His idols were the moon and sun
And he walked the hills with nothing on.

Chorus:
Singing I don't care a b*****
I don't care a b*****
I don't care a b*****
What anybody thinks of me.

The randy doctor in his day
Put many a girl in the family way
His little b*****ds could be seen
From Pontypwl to Pontyclun.

The Nonconformists did not like
The practices of Dr. Price.
They said he was not nice to know
He had an enormous libido.

So at the age of eighty-eight
The Doctor had to find a mate
He met a girl called Gwenllian
And became the father of her son.

A doting dad was Dr. Price
He called the baby Jesus Christ
He wrapped it in a flannel shawl
The bonniest b*****d of them all.

But one year later, sad to say
The Doctor’s baby passed away
So after chapel, one dark night
He set the little corpse alight.

The Doctor thought it was a joke
To watch the kid go up in smoke
He took the ashes with a grain
And put them in a biscuit tin.

But when the local deacons saw
That Doctor Price had broke the law
They shouted at him, “Ach y fi.”
And put him under lock and key.

The Doctor told the Magistrate
He didn’t care about his fate-
“It was the most hygienic way
I’ll be a famous man one day.”

The morning that the Doctor died
His children stood at his bedside
He drank a bottle of champagne
And started singing once again:

He told his children in his will
To burn him on Llantrisant Hill
They built a crematoriun
And the Doctor went to Kingdom Come.

It’s thanks to Doctor William Price
That modern corpses have the choice
To linger in the mouldering clay
Or go up the chimney straight away.
