Someone call the doctor, there’s a real lady-killer in Walnut Grove LITTLE HOUSE ON THE PRAIRIE, Steve Tracy, Alison Arngrim, Kevin Hagen, 'He Loves Me, He Loves Me Not, Pt. II', (Season 6, aired May 12, 1980), 1974-83 / Everett Collection According to Bright Lights, Prairie Dust, Landon, who was a key creative voice throughout Little House, cast actors who bore a strong resemblance to their characters.

He was also something of a lady-killer. As Doc, his mellow voice, wise face, and bright blue eyes inspired confidence, and few of us could have guessed he was a dedicated single parent raising a young son.” Doctor Kevin Hagen is in the house THE MAN FROM GALVESTON, from left: Kevin Hagen, Jeffrey Hunter, 1963 / Everett Collection Some of that lady-killer dignity might have come from Hagen’s upbringing. He was born to a pair of ballroom dancers, Haakon Olaf Hagen and Marvel Lucile Wadsworth. Sadly, Haakon did not stick around, and so Hagen’s mother, aunts, and grandmother took on the task of raising him themselves.

When he entered Hollywood, he landed roles in some of our most nostalgic favorites, including Lost in Space, M*A*S*H, The Twilight Zone, Knots Landing, Bonanza, The Big Valley, and Gunsmoke. By the time he entered Little House on the Prairie for a credit that would last from 1974 to 1984, he had several of these under his belt and was a veteran of both acting his character and charming his peers.
