Not a person, but Karen Hemmingham's "Summer is invincible":

When winter falls upon your land
And laces leaves in icy glow
When frost numbs every beast and man
To weave a winding sheet of snow

Ch Then in the midst of winter, when hope like death lies still
   Listen to the heart within singing
   Summer is invincible, summer is invincible

When clouds like foaming seas of grey
Drown out the blue of summer skies
When winds of steel forge through your days
And the light of summer dies

When blood red beads the hedgerow
And emerald spears of holly gleam
When poison pearls the mistletoe
And frost kills every dream
