Mem­oirs writ­ten by poets and nov­el­ists often have a spe­cial charm to them, even when they deal with dif­fi­cult and painful sub­jects, and Joe Dunthorne’s book, based on his family’s his­to­ry, takes this a step fur­ther, infus­ing ener­gy and inten­si­ty into the nar­ra­tive and bring­ing the read­er direct­ly into his remark­able adventure.

Dunthorne’s Ger­man-Jew­ish great-grand­fa­ther had been a chemist in 1933 in Oranien­burg, a small town just out­side Berlin, qui­et­ly invent­ing and bring­ing to mar­ket ano­dyne house­hold items like tooth­paste. But the Nazis had dif­fer­ent ideas for his tal­ents, and pro­pelled him into their spe­cial chem­i­cal weapons lab to apply his skill to cre­at­ing prod­ucts that were con­nect­ed to their mil­i­tary goals, prod­ucts like life-sav­ing gas masks and an increas­ing­ly potent set of poisons. 

Although he suc­cess­ful­ly escaped to safe­ty in Turkey with his imme­di­ate fam­i­ly in 1935, he left many extend­ed fam­i­ly mem­bers behind, only to lat­er learn they had been mur­dered in Auschwitz.

His guilt at hav­ing worked for the Ger­mans nev­er left him, and he put his sto­ry down on paper in a long, dark, com­plex trea­tise, some of which was writ­ten on his deathbed, and it became the major part of the family’s archives. This is the doc­u­ment that Dun­thorne found, decades lat­er, and which pro­pelled him to trav­el to cities across Ger­many and Turkey to find the true mean­ing of his relative’s expe­ri­ence. The result is this beau­ti­ful­ly ren­dered per­son­al his­to­ry, writ­ten with mature per­spec­tive as well as ten­der­ness, cross­ing gen­er­a­tions and tra­vers­ing coun­tries to expose the truth beneath the trau­ma and the tra­vail of his great-grandfather’s life.

Part of the intrigue involves the sin­gu­lar fact that the tooth­paste Dunthorn’s great-grand­fa­ther invent­ed, and which became a pop­u­lar item in Ger­many, con­tained radi­um, a chem­i­cal that is now under­stood to be poten­tial­ly dead­ly. At the time, though, peo­ple thought of it as a won­der ele­ment and used it in cos­met­ics, drank it in soda, and added it to but­ter and milk, believ­ing in its so-called health-giv­ing properties. 

Today, though, when hun­dreds of unex­plod­ed bombs in Oranien­burg are still buried in the high­ly irra­di­at­ed soil, still emit­ting alpha par­ti­cles with every rain­storm, Dunthorne’s sto­ry holds par­tic­u­lar rel­e­vance. He remem­bers his great-grand­fa­ther as a warm, lov­ing grand­pa, despite the fact that the man spent much of his life mov­ing into and out of psy­chi­atric hos­pi­tals, try­ing des­per­ate­ly to over­come his self-revul­sion at hav­ing helped the Nazis. 

Nev­er­the­less, Dunthorne’s sen­si­tive han­dling of this lega­cy of guilt brings us a sear­ing­ly hon­est look inside the minds and hearts of a fam­i­ly with the dark, painful secret of collaboration.

Born in Wales and raised in Lon­don, Dun­thorne writes in metic­u­lous prose that always invites read­ers to keep read­ing. It is warm and at times even radi­ant, as he writes about fam­i­ly mem­bers who touched him pro­found­ly. And in the wealth of pho­tos in the book, he shows the read­er their faces, filled with both emo­tion and information. 

The book will appeal to a broad audi­ence: sci­ence enthu­si­asts, Holo­caust sur­vivors and their descen­dants, pro­fes­sion­als who study fam­i­ly dynam­ics, and even those sim­ply look­ing to learn some­thing new. Dunthorne’s gen­tly self-dep­re­cat­ing approach and his deep and dis­ci­plined research com­bine to make a very sat­is­fy­ing memoir.
