thumb|The death of TankmaroThankmar (or Tankmaro, or Tammo) (c. 908 – 28 July 938) was the eldest (and only) son of Henry I of Germany (Henry the Fowler) by his first wife, Hatheburg of Merseburg. His mother had been previously married and widowed, after which she entered a convent. Because she left the convent to marry Henry, her second marriage was considered invalid and the couple split. Thankmar's legitimacy was, therefore, in question.
