Ruby split String into two sections and put in hash with predefined keys

I don't know if this is actually good ruby code, but what I am trying to do is split a String into two separate sections and put the two as values to two specific keys. For example:

  name_a = "Henry Fillenger".split(/\s+/,2)
  name = {:first_name => name_a[0], :last_name => name_a[1]}

I was wondering if this could be done in a single line through some ruby magic however.
