A device for recording both chronological events and physical growth events of an individual or group of individuals' lives. The device includes linear measuring device having at least first and second opposed sides. The first side has a linear measurement scale inscribed thereon and at least one recording surface associated therewith. The second side has a chronological scale, preferably in months and years, inscribed thereon and also has at least one recording surface associated with the chronological scale. Thus, physical growth can be measured on the first side and recorded on the recording surface associated therewith as the individual or several individuals grow physically. Significant events can be recorded on the other side.
