Constructing exhibitions such as Voyage to the Deep is the work of preparators, or ‘preps’. They are an integral cog in the machine of traditional museums and, as the name implies, are employed to prepare objects, specimens or exhibits. Originally they included embalmers, flensers and taxidermists as well as model makers and tradespeople. The museum has four preps, all of whom have visual arts degrees. Creativity is just as essential as practical skills in a job which requires us to exercise our minds as well as our hands.
