It's a fairly small part of my book case, but it's a significant one - Jurgen Moltmann, whose death at the age of 98 is being reported on social media, was - is - a significant and thoughtful theologian.  I remember reading both 'The Crucified God' and 'The Church in the Power of the Spirit' for undergrad essays.  I can't recall what either book said or what I wrote, but I do know that it mattered and made a difference to my thinking/understanding/theologising.

Moltmann's words will long outlast him, as they continue to challenge, inspire and educate new generations of theologians and ministers.
