Although you can kinda see this in the Task History - this is IMPERATIVE for large team like ourseleves when we are monitoring Tasks. Please HubSpot developers this would be an easy one to make happen.
Kind Regards

Thanks a mill, Shaun
Will check the task history to see how to ascertain who created this task
Onwards & upwards 
Very much needed! Seems like such a small fix but would be very helpful!
“Assigned By” in Task Property - please make this a thing HS!
This should already be in the product.
Kinda sad to see this has been sittin’ for 4 years…Admin’s need the ability to see staff’s tasks & break them down between self-assigned & management-assigned…
I was looking for the same info and ended up here. I’ve noticed something interesting. There’s a “Created By” field in Tasks. I’ve seen this field filled out with a user’s name in my client’s account for several tasks, but some entries are blank. I’m guessing those blank tasks are being assigned automatically from workflows. It would be really handy to know exactly which workflow is kicking those tasks out.
@JasonWofford Appreciate your reply! Just found the ‘Created by’ field recently, too & have created a Tasks view tab for my lead advisor to track where folks are on his specific tasks. Very handy.
also, however, as you mentioned, learned that tasks assigned via a workflow aren’t showing there. Bummer. Literally Yesterday started noodling on a way, property, form-fill space, something…within the workflow steps which would allow that info to flow in. Zero answers yet but if You think of one, lemme know! 
Though you can add the ‘created by’ field on the desktop version, the mobile app doesn’t let you do this.
So I cannot tell who has sent me the tasks when I’m on the road with customers.
This seems like bread and butter stuff, as Sales Reps work on the road and having to log into the desktop version each time wouldn’t be convenient.
Why doesn’t this ‘created by’ information for tasks exist on the mobile app?
I still need this property added to Tasks. I don’t understand why this has not been added yet. I can see “Created By” in the Task board view but it does not show me who last assigned it to me. It could have passed thru 3 or 4 people before being assigned to me and I have to follow the breadcrumb trail to find out who assigned it to me.
I tried to figure out how to add a new property to Tasks like I can for other records, but changing properties on Tasks is not an option.
This should be property in a Task that I can see on the Record itself, like this:
Agree 100%. And what about letting the “Assigned By” automatically know when it is marked as Completed?
Wir stimmer hier auch zu 100% zu. Es muss dringend als Eigenschaft filterbar sein, aber noch viel wichtiger ist es in der Aufgabe selbst zur Anzeige. I think @JStephens visual suggestion is exactly right!
Super important feature 
Agree. In my opinion, this is a basic requirement and my team have been asking for years.
Hi everyone! My name is Hallie, and I’m a Program Manager on the CXM Team. This is currently in development! We will update this post as soon as more details are available. Thank you for your continued feedback!
Hey @hhiggins is there any update on this? Maybe it’s the perfect time now to place this topic again there, because the build at the moment on the tasks
Hi @hhiggins It’s great to hear this feature is in development. It’s disappointing to see this basic functionality has been being requested for over 6 years without any progress. Like the other commenters have mentioned it’s a huge time waste to see a task assigned to you in the company, contact, or deal view, and have no way to tell who assigned it to you. It feels broken. Can you pull any levers on your end to get this prioritized and released?
