For manufacturer name, not description of:
All I did was put the following code in the customer/main/product.tpl:
Code:
<TR><TD align="left" valign="top">{$lng.lbl_manufacturer}:</TD>
<TD align="left" valign="top">{$product.manufacturer}</TD>
</TR>
... and now my product's manufacturer is in the product details page.
