A solution in F#:

open System

let proper (x : string) =
    x.Split(' ')
    |> Array.filter ((<>) "")
    |> Array.map (fun t ->
        let head = Seq.head t |> Char.ToUpper |> string
        let tail = Seq.tail t |> Seq.map (Char.ToLower >> string)
        Seq.append [head] tail
        |> Seq.reduce (fun acc elem -> acc + elem))
    |> Array.reduce (fun acc elem -> acc + " " + elem)
