Corgi, 1955, 188 p.

The humans on Mundis were sent on the last spaceship from a dying, fractious Earth and inculcated with an overwhelming compulsion against atomic power. They have formed a settlement with a large age gap between the space travellers and those born after arrival.

Unknown to them a later expedition was sent out, this time under military control, and it has been waiting on the system’s other habitable planet, Secundis. When confirmation comes that Earth has been destroyed the military ship sets off for Mundis to unite what remains of humanity.

That hierarchy is of the novel’s time in its attitudes to sexual politics, “Only a dozen women on the ship were so useful in one way or another, so indispensable, that their sex was forgiven them,” but in contrast to that McIntosh does try to portray a different approach in the society on Mundis where attitudes to marriage are less rigid than in our 1950s.

Thanks to two Mundans who have struck off on their own for a while the rest manage to avoid the Secundan party long enough to resist assimilation, an endeavour which does require their conditioning to be overcome.

The Born Leader of the title is one Rog Foley of the Mundans who is not as hidebound as his elders or the others of his generation but who is really almost incidental to the plot’s resolution.

This is a typical piece of SF of the middle 1950s. It almost seems quaint now.

Pedant’s corner:- “Mathers’ eyes” Mathers’s eyes,) “impressed by their significance of the occasion” (impressed by the significance,) “the list of elements stopped at eighty-eight” (in 1955 we were actually up to Atomic Number 100 – or 101 – but the Mundans in the book did not acknowledge those above no. 88,) a missing restarting quotation mark at the resumption of a piece of dialogue.
